ECM wiring diagram for '92 LS400
 

Anyone know of an on-line version of the ECM diagram for the 92 LS400?

I want to know if I can bypass the #2 knock sensor wire and run a new wire from the ecm to a new knock sensor that I'll just hard mount to something on the engine. It won't actually do any knock sensing but the other one is still there and working to do the job and this new remote mount unit will simply allow the computer to think it is there and working - though it won't ever provide any knock signal - so the ECM will give me back my full timing without having to rip apart the top of my engine.

Just an idea but I need the ecm diagram to know which wire to bypass.

Thanks for any help.

I don't know of anything free. This one is pay-

the very first link at the top of the LS forum titled "Service Manuals" is what you want :)

and its free ;)

The free one doesn't have complete diagrams. I needed the ECM related diagrams too.

Pay the $10/ day and go to the Toyota link above. (TIS)
