Please help no tach signal on pin 10?????
I have looked at all the posts on this and a few other sites and have my rpm window switch hooked to the number 10 pin on the pcm it is the right wire but I can not pull a signal the digital tach reads 0 on the screen of my new 8969 msd digital window switch. We thought the unit was bad but hooked it up to my explorer and it reads fine. So from what I can tell it is hooked to the right wire and the unit does work......Im lost please help if you have had a problem like this or can shed some light.
