1988 B250 Wiring Diagram - Fusible Link
I'm getting a 1988 b250 but it's having some power issues. from all my research these are actually pretty common problems and related directly to the fusible link behind the brake booster. What I'm trying to find out, and the reason I want a wiring diagram, is to see if I can replace that fusible link without having to pull the brake booster.
the current issues are not charging, no headlights, no tail lights, no parking lights, no brake lights, no dash lights, and no door locks.
any help would be appreciated. I've already done tons of research just in this group and I've located where they're at I just can't locate a diagram that specifically lays down the colors of what each one does so that I can test. once I can test the wires I can verify which one's bad and probably splicing without having to pull the brake booster.

Get a factory service manual for your van. It will make working on it SO much easier. Should be available on ebay, and the like. Keep in mind though, you want the FACTORY manual. Not haynes, not chilton. FACTORY.

I asked a question because I don't have the factory service manual at this moment.
the other reason I have two questions because even if I ordered it today I need this fixed before it would arrive.
it just means if I don't get the information I'm hoping for I will be taking the brake booster off.
