1990 F53 starter relay wiring


New Member
Hello everyone, I'm new to this forum and looking for a bit of help. I have a 1990 class A on an F53 chassis with a 460 7.5l. I'm trying to get help with the starter relay, for some reason I keep frying mine and not sure it's wired correctly. Hoping someone know the correct wiring for it. I have read alot of wiring diagrams, but my knowledge of wiring and electric systems is noobish. So what the original wiring was: on the battery terminal it had the battery cable, a 2 wire connection with one big black w/yellow stripe and one yellow wire, and a 2 wires connection with a black w/gray stripe and a black wire. These ones connected at the harness to a black and yellow wire. The ground cable on the other terminal, and a small yellow and brown wire on the s terminal. There is also a yellow wire coming off the fuel pump relay, but not sure where it goes. Any help would be greatly appreciated. I have tried to post pics, but they are to large, will try and resize and repost them
