I have a question for the technical crowd. I have a 1992 4wd 5spd 22re chassis and a rebuilt 22re with 50 miles on it. Engine is from a 1994 pickup. The PO mixed parts and as far as I know, I have a 92 ECU with the section that goes to the tranny, however my distro cap to ICM was 92. I'm wanting to go to the 94 since the engine is 94. I've bought from the plugs to the coil as of now. The question is can you splice the 92 hoop ring wires to the harness connector of a 94 and hook it to a new 94 ignition coil. The coil ohms for 92 is 1.8-2.0, and 94 coil is .8-1.0.

Since I dont think hooking to the lower ohm coil will work and I get a 94 ICM, will it interface with my ECU at the correct ohms, plugs, etc. They look the same in the stores minus the coil wire plugs/ends.

Should I go with a 94 ecu and re-splice the harness, and get a new ICM?

This is a new engine and I don't want to mess anything up but I want the best stuff for it.

It did work before and I do realize that the 94 distro cap nodes are offset so I will have to re-time it.

Other notes:
I am having the issue of when the gas is pressed, the engine hesitates/misses for the first 3 fires or so then smoothes out. I'm pretty sure it is timing though but I would like to get it to the better 94 stuff and time it once and be done.

Thoughts / Ideas are welcome.

oh and for mileage, 375k on the chassy and 50mi on the rebuild with Thorley headers, new crank, new AFM, O2 sensor, and pretty much everything new inside the engine. I have new vac lines that I haven't installed yet but I plan to. I also put in those ebay injectors which seem like junk so that could be my hesitation problem. It's so old, it could have many issues. I eliminated the resonator from the intake to the header rail. And I got it bored 3 over.

It was kinda hard to follow, but I'll do my best...

First, the 22re dosen't care which year you go with, but you need to pick one or the other for those years. The ignition system is slightly different, the coil and the dizzy. If you have a complete 92 harness, ECU, and ignition system...go that route. You don't want to have to splice systems together because they will never talk right to each other.

All 22re blocks are the same (86+), it's just the different intake's and ignition systems that were put on. Then what complicates it is all the emissions stuff between federal, cali, Canada etc...

Use the 92 stuff...

I want the newer parts that the 94 has like locking plug wires. I don't know if the engine components are 94 or 92. I'm still lost there. if they're 92 then I'll stay there. I have something wrong with the speedo and i keep getting code 42 so I'm trying to move to all new 94 stuff. I have a 94 harness and ECU that I can get ahold of. I'm hoping it'll fix the speedo since I've tried checking the wiring to the VSS, a new 92 ECU, and a new cluster. I don't know if the code 42 is putting the ECU in looped mode at all so I want everything fixed. There isn't a CEL right now though.

Here are the parts I want to interchange.

Import Direct Ignition - Ignitor

Import Direct Ignition - Ignition Control Module

Part # 14-0201 for a 94 Toyota Pickup DLX 22re



These parts are almost exactly the same. I just don't know about the ohms that the ECU sends. I may test it and see since I bought new 94 coil, wires, distro cap etc.

You lost me.

Keep it simple. If the truck is a 92 and you have all the 92 items, stay 92.
