Default Help with LTCC install

I have a 94 and have gotten the car started with the LTCC. The two pink wires are connected to the pink with black strip, which went to the factory coil and I have the white wire connected to the yellow/white wire(discolored) on the ignition coil module. MY tach isn't working and my ASR service light is on. I know once the tach works the light will turn off.

THe plugs for the coil and the igntion coil are not plugged in. Any help with this will be appreciated. Thanks

I've heard that when installing systems such as the MSD, you have to bypass the tach filter. That may be the case here also, but I'm not sure. Hopefully someone else chimes in with more info.

Thanks for the help Mr mojo and Bob had the same reply. I got the tach working and Bob emailed me more instructions on how to get the Service ASR working properly.

FYI - the tach and ASR are the same problem with this install.

The ASR needs the tach input... glad you got it!
