Wiring the engine harness to the MS harness has been pretty clear except for some uncertainties with the CKP input and what our setup is capable of. 57 in car for the first time and am running diagnostics. I am using a preassembled ms3x system with a 3. Everything checks good in the engine harness. That will be plenty for a stock boosted engine. i will update this as frequent as i have questions which im sure will be alot due to this being my first car ill be wiring up myself. This is for a rear engine. I have a couple questions I have some resistors to be able to run TFI as well as the ms3x card so I can easily run my PWM IAC and my A/C.
