Drawings or Pictures

[crazedyak]

Does anyone know where a decent drawing guide (Schematic or Picture guide) of a 1987 K5 for the electrical system?

I have the drawings from the Haynes manual, but there are so many things hidden behind the dash I would love to have/create a cheat sheet to help out someone else in my shoes later on.

I'm currently on the hunt for the Door Lock Relay, and the A/C Blower Relay. Thanks for the help!

Should have a DK BLU wire coming off of the resistor at the firewall / blower motor. This wire also runs to the A/C blower relay. It's shows in my GM WD manual to be on the engine side of the cowl.

Door lock relay should be up under the dash. Sorry no further info on that one.

Let us know once you pin point them though.

Thanks,
