Are all black ICM's the same and are all Gray ICM's the same?

The PIP paths are working correctly and I will check the TPS Voltage when I put the computer & a black ICM back in. What should the voltage be?

Can I used either computer with the Black ICM?

No some are distributor mounted and some are remote mounted.

.07-1.0 VDC closed throttle. About 4.5-4.9 VDC WOT.

No the 89 needs a gray module and wiring (and you do not have wiring for if [no start wire]).
The 96 needs the Black module.

Subford,
I found the differences in the modules, i was wondering if the big blocks and other v8's used the same modules. If they had the same type out of the 4 possible.

I have been able to do more searching and have found out the injectors and other items are not getting power with the key on, so the harness is screwed up somewhere. Is there any difference with the "underhood truck" harness whether it is a small block, 300 or bigblock? Are they all pinned the same at the square connector near the fuse block? Are they the same from 92-97 (old body style)?

Trying to narrow down the problem to see if it is in the engine harness or truck harness under the hood. Does anyone have a pin diagram for the square plug near the underhood fuse block?

No you would not have any power to the injectors as they are powered by wire #361 a red wire.

Here is why:

Thanks for the information and your help.
I wonder if they changed the connector in 96 because of Mass Air on the smaller motors?

Do you know if the 95 pin layout is the same as any other years? (92-95?)
Or is each year different, so I need to re-pin the connector?
Do you have have a listing which describes which three digit wire goes to what part?

Your going to have to give me more information.
Are these all California trucks that you are talking about?
I see you are in Minnesota but you talked about SFI 460 trucks and that would mean a California truck for 1996.
Does the 1995 4.9L truck wiring from the 1996 computer to the engine plug have all the wires for 8 injectors?

The 92 - 95 460 trucks are not SFI so the wiring would be much different.
Maybe the 1995 California truck 460 was SFI.

That would be the Computer to truck wiring diagrams and I would need the exact truck you want it for and I would need to email them to you.

All the parts and trucks I am working with are not mass air, they are all speed density.

Isn't mass air only available in 96 trucks for the 300, 302 and 351?
The 460 was only mass air in 96 and 97 with California and possibly massachusetts trucks?

Current Parts I have:

Truck: 1995 F-150 originally a 300 Speed Density 2wd E40D(?)
Motor: 1989 460 Speed Density ZF (also have ICM & PCM from this truck)
Engine harness: 1996 F-250 460 E4OD Speed Density (also have ICM & PCM from this truck)

The image below would be close to what you have for wire numbers and colors. The pin numbers are for a 1996 4.9L.
The pin-outs I posted above still apply.
I think 1992-1995 are the same pin-outs for the engine plug.

Thanks again for the help.

I have compared the female engine harness and to the male truck harness and have noticed several differences.

The female plug on the engine harness, has theses connections with out a match.
6-651
8-101
10-347
20-883
30-570
35-917
40-387
41-388
42-361
The male truck plug have theses with no match
15-310

I wonder if those extra wires without a match going to cause a problem? Or are the wires missing a match on the engine harness for Mass Air 460?

The local junk yard has a couple 96 F-250's in the yard and I am debating about picking up the under hood truck harness. Now my question is, are the dash harnesses different from 95-96? Especially at the firewall plug.

I started pulling the engine harness apart to re-pin it and noticed that the the the 42 pin is a larger size and could not be moved.

So I went to the junkyard to see if they had a 460 truck. I found a 96 F-250 460 E4OD Speed density (i think, intake was missing). I bought the under hood truck harness and the instrument cluster since it has a tach. I also bought the ICM and PCM to have for spares. I the computer had a hypertech chip plugged into it for a bonus.

Will these items work with my cab harness or do I need to pull the one out of the junkyard truck? The junkyard truck has some cut wires that needs to be repaired and it has some sort of alarm wired into it which I would remove.

jk89cat thanks,

If you can check to see if a 1996 F-250 460 SD has the same dash wiring as a 1995 F-150 300 SD it would be much appreciated.

It seems like they may be different, because some posts say the gauge clusters will not swap.

If the weather is not bad tomorrow, I might pull the dash wiring before the truck is gone to be on the safe side. I think I should be ok with the tail light and fuel pump wiring on the frame.

The 46 361 Red wire is your main power wire to all the injectors, solenoids (A.I.R.) and relays and carriers the most load (current/amps) so it should have a larger pin and wire.

jas88 has a very good reputation on FTE.jas88 has a very good reputation on FTE.jas88 has a very good reputation on FTE.jas88 has a very good reputation on FTE.
I am confused on something - when you say "engine harness", do you mean the one that is connected to the engine itself (like the injectors and the distributor and such) or do you mean the engine COMPARTMENT harness, that connects to the ECU and then goes all the way around the fenders and core support and connects to the headlights and such?

The reason I ask is that I had to swap that on mine when I went from 300 Six to 460 as the 300 had the TFI module on the distributor but the 460 had it on the fender. My truck would not start until I did this because there was no spark from the coil, as you can imagine, since it had no TFI module.
