I dropped an s13 blacktop into my 97 the other day, and I wired up everything according to
this. When i connect the negative to the battery the ECU relay clicks VERY fast and doesnt stop, i played around with the SR F10 power plug and the ECU turned on fine with no click, but it keeps happneing every once in awhile so obviously this is not good. What could cause the relay to click like this? bad grounds? short? Anyone else experience something similar? TIA
