you can just use the green wire trick...

I just don't like running extra wires.

put a 1K 1/4 watt resistor in your diagnostics box between IG- and B+

the stock ECU used to provide this pullup to power the tach signal, since we removed the ECU, we removed the pull-up, this replaces it.

hmm I have a 92 using a MS1 and I didn't have to touch anything for keeping the stock tach working fine, works without adding any mods to the MS for tach and messing with the car

just for info, running a MS1 pcb v1.01
But I don't see why that matters, as I believe that the stock dash 1.6 tach runs off either the coilpacks or iginitor

You can lose the tach if you damage your ignitor.

pins 1-2-7-8-9-10-11-12-13-14-15-16 are already connected together. on most installs I simply run 4 individual grounds out the the 4 oem ground wires.
