Connecting MT-2500 to 1988 Ford E-150 EEC-IV

[user00293]

Hello,

I have an older 1988 E-150 Okanagan Camper Van with a 4.9L V8 I'm restoring.

The Ford factory manual has no information about connecting an obd1 scanner.

It does have information about the EEC-IV modual and it's pinouts, but nothing I could find about connecting a scanner.

I did find a couple of EEC-IV diagnostic connectors under the hood.

I do have a EEC-IV connector somewhere for an Innova 3140 however I don't know if it would work with the MT-2500. The Innova 3140 display no longer works and Innova won't repair 3140's if there's no letter designation. They do offer a replacement for ~$200.00.

I have a couple of modules that I've used with an OBD2 98 Jeep. Primary Cartridge GM-Chrysler-Ford Jeep MT25001001 and Troubleshooter GM-Chrysler-Ford- Jeep MT25002900.

Plus some personality keys: K-1, K-2, K-2A, K-3, K-7, K-9 & K-13

The MT-2500 cable has an OBD2 adapter/connector with personality key slot.

So I found a found a Ford 7 pin OBD1 to OBD2 Adapter

Do I have everything to connect to the 88 Ford Econoline ?

I believe you will need the Snap On Ford adapter for OBD1 Fords and also a battery or lighter 12v power adapter plugged into the side of it to provide a power source.

So the Ford 7 pin OBD1 to OBD2 Adapter won't work in place of the FORD-1 adapter?

They have the same 7 pin connectors however I'm not certain if the obd2 to obd1 adapter supplies any power?

I did find this url about Connecting to OBD-I Vehicles

https://www.snapon.com/Diagnostics/US/KB/Connecting-to-OBD-I-Vehicles.htm

It lists a Ford 1B adapter, which is similar but different from than a Ford - 1 in that it appears to have a 12 volt power connection. I could not find any information about the obd2 to obd1 adapter supplying power, which would I suspect would need to come from the MT-2500 15 pin connector, which I doubt would have as it's disconnected from any vehicles OBD2 (that normally supplies pwr to obd2 scanners) . It appears to connect to OBD1 EEC-IV would require a FRD-1B connected to a 12 vdc power source.

FRD-1 adapter (has 12 vdc pwr jack)



Ford-1 adapter (no 12 vdc power jack)

I went ahead and found a SNAP-ON Scanner ADAPTER FRD-1B MT2500-20B for $13.99 with shipping from eBay. I mostly want to confirm the information I have on connecting to obd1 eec-iv using a mt-2500.

Ford-1 adapter

I'm not sure what scanner that OBD2 to OBD1 connector you displayed is for but I wouldn't want to waste my money or risk bricking my MT2500 if the pin out to the Serial cable differs from the Innova brand or whatever it is for . If the 12V or ground from adapter route to different pins on the MT2500 scanner. It's a Cr@p Shoot like buying an HDMI to 9 pin serial cable adapter from Chinaman Town and expecting to
that your MT2500 screen will be displayed your big screen HD television.

I'm not certain what those ob2 to obd1 adapter are either but they have quite a few on eBay which can be found when purchased from China for around $5.00. They are sold to work with specific vehicles such as Ford, GM, etc.

I first started using PC's back in 81. My first PC an Osborne One, ran CP/M using a ~4 inch display 64K memory and 4 mHz zlog z80 processer. PCs before graphics were fairly fast.

https://en.wikipedia.org/wiki/Osborne_1

Now the new PC's are fairly fast again if you have a SSD drive. Recently purchased a P300 Thinkstation, 16GB, i7 (4th gen) with SSD drive, boots in approx. 30 seconds. However PC's cpus have sort of become maxed out even though they can add more transistors they haven't yet found a good affordable method to reduce the additional temperature created. So we haven't lately seen much of a cpu speed increase. Memory has improved but still is mostly DDR3. DDR4 is still expensive used mostly for gaming.

Video resolutions have significantly improved however I don't game and my Nvidia Quadro K4000 with 3GB memory is more than enough for my video needs.

I have a NEC 32" V323-2 display monitor, even though it has a tuner module I only use the LCD monitor to connect to a PC and don't own a standard hd television. The LCD tv's owned in the past all went belly up due mostly to their backlight burning out. Newer ones are suppose to last longer using led backlights.

Anyway I'm sticking with more reliable brands such as NEC. This one is built a little better than most consumer tvs as it's built for commercial use. https://www.necdisplay.com/p/v323-2 . Maxed out at 1080p, doesn't have the ultra high res but should last a while.

The picture you posted of the side of the Ford adapter , I think the center pin in the barrel appears damaged and bent off to one side, so I would take a pass on ordering that one

Nah, I think it is just the angle of the camera.

The FRD-1B MT2500-20B adapter purchased didn't have a pic. Seller has 100 percent rating and 30 days for returns.

I do have an Innova 3140 however the LCD became skewed and unreadable and Innova will only replace it for $194.00. After spending over $200.00 for it I think it would have been better to have gotten a less expensive obd2 scanner with live readout as I don't used OBD1 very often.

My 88 E-150 has 4 pin OBD1 connector

Received the Snap-on FRD-1 adapter connected to 12 volts and the MT-2500, went to connect to the E-150 OBD1 connector near the battery.

However it appears my primary GM-Chrysler-Ford Jeep module is too new and doesn't support OBD1 as It's labeled to support through 2000.

When I connect and turn on the MT2500 it displays a message that the currently installed primary module supports vehicles from 1996 and OBD2.

I think I may have an older module somewhere that supports OBD1, however I can't recall where I stored it.

Looking around on eBay I've found a few modules that should support OBD1 however I'm not certain of any differences.

e.g. There is a MT-2500-1293 and a MT-2500-1393 for Ford 81 - 93

Then there are GM-Chrysler-Ford Jeep primary modules that are good through 1999. Which may support OBD1?

I think GM-Chrysler-Ford Jeep primary modules that show through 2000 support for OBD1 was removed?

So if the GM-Chrysler-Ford Jeep primary module through 1999, does support OBD1 I'm wondering if there are any differences with Ford OBD1 support when compared to the MT-2500-1293 and MT-2500-1393 for Ford 81 - 93?

I found a Primary cartridge Ford 1981-92, MT2500-1292 and a MT2500-1392

Also a GM-Chrysler-Ford-Jeep Primary cart MT25001099, good for vehicles through 1999

However I'm uncertain if the MT25001099 has OBD1 support.

Bluepoint Microscan scanners

Found a set of 8 MT2500 modules on eBay for just under $70.00 with shipping. which is approx. $8.50 each for each module.

The MT25001099 module is the one that's needed for OBD1 GM-Chrysler-Ford-Jeep vehicles.

MT25002499
MT25006399

I've been looking around at various scanners to replace the Innova 3140 (OBD1/OBD2) that stopped working.

Came across a slightly used Bluepoint Microscan III EESC720 and decided to purchase the Microscan III as it has valuable software to connect the scanner to a PC and does both OBDI and OBDII.

Also purchased it's OBD1 cable from Snap-On. EAX0069L15A MICROSCAN III OBD I CABLE

The Microscan III is OBD1 capable if one has an EAX0069L15A cable and the correct Snap-On OBD1 adapters for an obd1 vehicle.

Snap-On sells several OBD1 adapter kits, some which include an OBD1 EAX0069L15A cable for the Microscan III. (Earlier ver. Microscan's used cables with a 15-pin connector which was changed to another type of connector with the Microscan III)

Connector for Microscan III



So I'll have both the MT-2500 and the Microscan III to compare any differences in OBD1 capabilities with my Ford OBD1 vehicles.

I have a freind who has a 92 Jeep Cherokee that's OBD1. I told him I would connect my scanner (using a Chry-1 adapter) to determine what sort of capabilities his ob1 pcm has.

The Cherokee and other Jeeps between 86 and 90 were Renix Jeeps. (uses the Jeep-1 adapter). After 1990 the Cherokee and other Jeeps became OBD1, 1996 was a transition year depending on what part of the year produced some Jeeps were OBD1 while others OBD2.

Connecting a Snap-On MT2500 to an 89 and other years Renix Jeep produces live readout.

Requires an older cartridge with OBD1 as OBD1 was removed from later version OBD2 cartridges.
