I had pull my engine back in December of last year. Unfortunately I didn't tag the power and ground wires. I did take some photos, but they are were left on my work laptop and I have since changed jobs. I beleive there are like 3 splices coming off the harness by the fire wall. I just need to know where these guys go. I wasn't thinking at the time and I didn't tag them. If anyone has any wiring diagrams or pictures could you please post them or email them to me at
clowe@borgwarner.com.
Thanks.
