i have a 1989 toyota pickup 22re, 5spd, ext.cab,with a/c,

i need to replace the cab wiring harness, can anyone please tell me what years/options the donor can be? or maybe what all information i need to match mine up, thanks

 

If it was me I would start with the Toyota Electrical Manual and go from there. This is what I do when thinking about a engine swap or any electrical problems

Just curious as to why you need to replace this??
