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
hmm

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

Braineack 09-01-2010 09:25 AM

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.
