Looking for 1995 1MZFE Wiring - Toyota Nation Forum : Toyota Car and Truck Forums

QuinnR2 · 03-17-2010, 02:06 PM

So I'm in need of 1995 1MZFE wiring diagrams. I'm mid-swap and am trying to wiring my OBDII port to the car so I can use my computer to diagnose why the engine won't stay running. However, using the 1994 wiring diagram at camrystuff.com doesn't provide what I need accurately enough.

What I'm looking for is the signal wire for the OBDII port (it's a white wire) on the ECU. The 1994 guide led me to a wire it said was white, mine was brown. No luck with that wire working.

I used the search function, didn't find anything.

Thanks in advance everyone!

In case nobody comes up with a free one, you could always do a 2-day subscription ($15) to Toyota TIS (techinfo.toyota.com) and download from there.

Hm. Well I'll have to give that a go tomorrow if nothing pops up. Thank you!

Have you tried Haynes manual? It contains wiring diagrams too.

QuinnR2 · 03-17-2010, 04:33 PM

I haven't checked Haynes yet, only because I never used them and don't know if they contain in-depth enough information. If they do, then I'd be all for it, but I never thought Haynes had ECU wiring.

I'm sorry, not sure which pdf you're talking about? The downloaded one from the toyota tech site?

What was swapped from where to where?

Prolly have my head up my @ss but wasn't the 1MZ new in 95, so shouldn't the colors be good?

Edit: ah - a 91MR2 perhaps?

QuinnR2 · 03-17-2010, 09:16 PM

1MZ came around at least in 94, I'm pretty sure at least. I could be wrong though.

But yeah, 91 MR2

You know, you also may look on factory manual for Gen4 camrys (also on camrystuff.com). The engine is almost the same there (I guess, the biggest change is VVTi, I am not sure when it was introduced, though).

Ive browsed through the camrystuff.com gen 4 stuff, however I can't find the wiring schematics like gen 3 has listed...am I completely missing something (I'm fairly good at overlooking things)

On the Generation 4 page, right below all the FSM sections, there is a link to "Electrical Wiring Diagrams".

Ha. Would you look at that, skimmed right past it because it's bolded! Silly me!
