does anyone knows how to wire the rb26 into the skyline gts/??
it came with an rb25de an was swapped with the rb26dett but no one knows how to wire it in, they tried it but burnt the computor already, but the plan is to get the other computer and the wiring diagram..
if any knows i`d like sum assistance and sum diagrams ....thanks in advance.
