FOURTH: Green Wire - TACH Terminal from the PCM
Locate the PCM (Refer to a shop manual for location). There are two slots of connections for the PCM. The upper part (which is BLUE) and the lower part (which is BLACK). Using a wrench, unbolt the lower part (BLACK), making sure not to damage the gasket. Remove the light blue face for easy access to the wires. Locate PIN #10, it is WHITE WIRE. Remove some of the electrical tapes for more access to the wire.
Cut, strip, and connect the white wire to the Green Wire from the TACH. Use a connector butt to properly connect the wires. Tuck neatly all excess wires using wire looms and electrical tape.
Im thinkin that would get rid of your stock tach? It looks like it reads that you dont reconect the white wire to itself? What exactly is the white wire, is this where ive supposed to have hooked up my shift light this whole time?, etc... even if i should have a tach adaptor you guys said it would still work and just read half the signal. I could just double what i want it to blink at... It bothers me that it sits there and doesnt work. Im kinda lost on what to do. Ive tried the wires above the coil packs, nothings worked.
