Im running a pnp ms1 v3.0 in an 89' 325is. Im trying to get the tach working through ms. JS10 is already jumpered to IAC2B, and im wondering where to go from here. Any help is appreciated. And i have searched other threads, but i've seen so many different options that i felt it was just necessary to ask myself.

I've tried all hardware options listed on the ms extra site and couldn't get it to work on my 318i. Interested to hear the answer to this thread.'84 318i M10B18 147- Safari Beige

what you're talking about doesn't work on MS1.
AFAIK the only real option for MS1 is to connect the tach to the coil -. a jumper over to the coil wire from MS to the tach wire should work.
the problem with this method is it only works with a single coil setup.Comment

My car is just running off of a single coil, but i guess i was following a ms2 setup? Happen to know which wire i should be looking for off of the tach?Comment
