Hi All, I’m looking for a wiring diagram, specifically for headlights, for my 1990 SJ70 Sierra. Lots of diagrams online but can’t confirm what’s correct. Anyone got a link they could share?
reason…. Jumped in the car a few days ago to find battery flat. high beam indicator light on, even with no ignition or headlights on, taillights and various other things not working at all. Taillight fuse was blown and as soon as I put it back in blows again.
Disconnected various plugs and accessories and found that when I unplug the blue connector for the factory loom under passenger side of dash problem goes away. This loom comes from the fuse box and heads out into the engine bay. Also found with that loom plugged in, if I disconnect both headlights, problem also goes away. Current thinking is I have a short in the lighting wiring. Wanting to see which direction wires go from a diagram before I get cutting looms apart! Any tips appreciated
