little update ive been looking at the wrong thing completely I was looking at a regulator I think, I fount what I think is the tscu on the right side of the battery box. it has a 4 prong plug and a 6prong plug. the wires on the 4 prong are all torn and raggety I fixed them but still nothing. so I just place a 2 prong flasher on which wires ? and ditch wich wires

As Ed pointed out a repair manual can be found on the Basscliff site.
It also has coloured wiring schematics.

another question sorry to bother again, but what if my tscu is fine, how do I check ? ive noticed I don't have any clicking or anything, not even a flash on the instrument cluster? would a tscu make everything go black ? p.s. im getting power to the 4& 6 prong plug going to the tscu. but I don't know how to check it. im having lack of knowledge.
