check engine relay? elecrical schematics needed

[fastNYsix]

I'm working on ls swapping my 86 v8 regal and I am having trouble finding electrical diagrams. All I can find are the schematics for turbo cars. I'm looking for info on the v8 cars. is this a relay of some kind? there's a few resistors on the board inside this relay looking thing behind the glovebox. The yellow wires go to the engine light and the aldl plug. I pulled the board out and the light goes out. would this car have had an ecm? I bought it as a gutted roller. I'd like to know what wires go where. thanks for any help.

"No, these are not the droids you are looking for". Sorry, could not resist the Star Wars quote!

Thanks for the website info. A bunch of good info on that page.

thanks there is a lot of good info there but I cant find this relay on those diagrams.

yes that would of had an ecm and of been a ccc system.the connector your holding i believe is the c.e/s.e.s lamp driver but may be wrong

could also be the vehicle speed buffer,the diagrams i have are fairly vague

Ok thanks. I bought a chiltons electrical manual online. That driver / relay definitely activates the check engine light. But I'm not sure how? There's no contacts like a normal relay. Just resistors. I think the speed buffer thing is green, over on the drivers side?

IMO, the best source for this kind of diagrams is the OE shop manual. It can be bought on CD or paper. Here's a set on CD...

Yes, the speed sensor/buffer is the greenish box

Thanks, I might end up getting that one anyway. I figured at $15 I'd roll the dice on the chiltons.
