Hey I'm finishing up and engine swap

https://www.yotatech.com/forums/f163...ex-cab-281733/

and I'm trying to pick up my heat and oil guage wires off the guage cluster and without ripping my cluster out where can I pick them up?

I've searched the passenger side harness and would like to avoid ripping up my drivers side fuse cluster if I can. I'm pretty sure I'm looking for a blue/yellow (coolant temp sender) and black/yellow (oil pressure sender) atleast up to the guage harness, any help pointing my to the right area to dig is apreciated.

There in the 2 body harness plugs in the passenger side kick panel. You need the wiring diagrams to find which pin it is though

Thanks for the quick response Jason that narrows it down.

In my case my ecu and engine harness are gone, that leaves that harness which is what I'm asuming is the body harness that's in that bracket beside where the ecu sits, I didn't see the coresponding coloured wires in there but maybe the cluster end changed form year to year? anyone with a 92 extended cab V6 know this?

edit*
further thought has lead me to the fact that this should be easy if I can just trace the old engine haness wires to the pin on the body harness.

Yes that's them. Find them in your wiring diagrams and it will show you the PIN number and color of the wire. If I recall the plugs are IH1 and IH2. One grey and one white plug

The two connectors connecting the cowl wire to the engine wire are ID1 and ID2 (IH1 and IH2 is pretty good for an off-the-head recall). The wire TO the temp gauge is pin 18 on ID2 (color Y-G), the wire to the oil pressure gauge is pin 15 on ID2, color Y-L.

This is all from my schematics; I've never taken it apart myself.

ya I found them, the silver hashes on the wires threw me off, thanks guys. Would you know which one is for the tach signal wire?

Pin 12, color B.

Awsome you guys are beign so helpfull I have yet another question for you.

The tach is built to take a pulse from the coil so if I take that same signal from my new inline 5 cylinder do you think I'm going to be reading 5/6th lower on the tach? or does it somehow just take a pulse of the alternator per revolution?

*edit

I think I've got it figured out no worries
