Hi everyone,
I've spent several hours searching this and other forums on this matter and I can't seem to find the answer. I'm doing an H22 swap into a '99 Civic DX. I'm using the P13 ECU, modifying the Civic harness, and the engine is from a '93. I've been wiring it up and that's been going fine, until I got to the distributor. The 8-pin distributor plug on the Civic harness has all 8 pins filled, but in the diagrams it shows that there is a 9th wire, a blue one, that goes to the tach. It doesn't seem to be here. On the H22 distributor, 7 of the 8 pins are filled, the missing one being the Black/Yellow power wire, which is on a seperate 2-pin connector along with a Blue wire (which I guess is the tach wire). Where is this blue tach wire on the Civic harness, and where does it need to go?
