So I generally use this FSM online - https://www.ether3al.com/93fsm-mobile/ and print stuff off when I need to, but I cannot find wiring diagrams within anywhere

Anybody have any good free resources for wiring diagrams or should I just break down and finally buy the hanyes manual, ha?Had an 02 circuit CEL on and I was wanting to verify the wiring is good before throwing a new o2 on.

 

This is for an 87

 

You didn't specify what vehicle you need this for. I have the overall EWD but it is 90-95 4runner, I don't think the O2 sensor circuit would differ much though.

 

 

Before you purchase a Haynes manual, consider signing up for the official manuals through TIS: https://techinfo.toyota.com/techInfo...pmanager/t3/ti

$20 will get you two days. I'm sure it's changed since I was a "member," but I was able to download enough to keep me going for the past 15 years. I happen to think the Haynes manual is perfectly fine, but nothing beats the real thing.

 

I didn't even think about this - thanks!

 

TIS seems pretty thorough and you are able to download pdf's. Though those looking for pickups, make sure to select truck rather than pickup. selecting pickup yields zero results

 

If I were to say...post some pdf's of wiring diagrams that other folks could use that I may or have not gotten from this, would that be OK?

 

Absolutely, you can share. We don't know where they came from anyway!
