I'm doing the auto to 5spd conversion along with my GTE conversion on my car. I have the 5spd ECU as well as the 5spd engine harness. What wiring issues am I going to run in to? Any advice on how to solve them? All I can think of is the dash harness not having the clutch safety switch in it. Also, will the W58 speedo gear fit in to the R154 trans to make my speedo read correct? Let me know guys.
