hi - having a load of trouble trying to figure out why my turn signals are not working right . checked all the bulbs and fuses.
would love to find a wiring diagram for a 1990 g20 5.7 to assist me in tracing back the issue; the haynes manual i have falls short.
thank you in advance,

Hi guys. Trouble shooting a turn single problem and now that the steering column is all back together this is just hanging there. and I can't figure out where hell it goes cannot find single connector that it would fit. It's coming out of the outer sleeve on the column. thought maybe it goes to the fuse box but still don't see a spot for it... thanks!

Don't double post please. Black wires are usually ground.
What do you mean by your Haynes manual "falls short"? What are you missing?

oldchevy

This gives you the color codes of the wires and black is ground.

thanks guys-
@mountainmanjoe sorry, didn't realize i was double posting. this felt like a separate question - to which I still don't have the answer but for now I think i'm okay not knowing. and to answer the other question I The haynes manual wasn't giving me the details i was looking for. I'm sure what i needed, like what certain wires did, was in there somewhere but it was incredibly tedious trying to find the section that correlated with the what certain wires did... etc.. . it's all good now. the other link helped a ton. it laid it all out nicely in a way haynes doesn't.
so yeah, @oldchevy and that wiring link from jalopy journal helped immensely with sorting out a ton of wiring issues i was having with turn signals etc. thank you!
