1988 GMC C7D w/8.2l Detroit Diesel...Wiring

So, the wiring of this is ... um... sketchy. The dashboard has random blinking indicators here and there (and one of them has an associated dinger... which is annoying... ding.... ding... ding...ding... you get the picture)

I was looking for a fuse panel. No luck. Maybe I'm not looking in the right spot? Or the fuses are inline?

Anyway, what I did find, is this diagram behind the seat, on sort of a vinyl sheet that maybe was attached to the hood or firewall at one point? It seems to correspond to a couple of rows of terminal blocks.

Is that it for this truck? All the wiring meets at the terminal blocks... follow it from there... ???

 

Maybe. I looked... but I haven't laid on my back on the floor under the steering wheel... which is probably what I'll have to do this weekend.

It amazes me... and it doesn't amaze me... that a vehicle that could fit three men a donkey and a gorilla in the empty space in the engine compartment under the hood... wouldn't have a nice, accessible fuse panel. Nah... they would have to stick it up under the dashboard, where you have to lay on the floor on your back to see it.

Of course...
