GM Ign Module Wwiring
That diagram makes it a lot more clear to me. I was confused by the terminology. Like you said, it looks like the the white wire is triggered by a separate PCM. Not sure I can make this work with a magnetic pickup trigger. Oh well - I'll use an older style 4-pin HEI module. I appreciate the help.
Those labels don't make sense to me. The "usual" GM module and the Mopar 4 wire module hook up exactly the same, "functionally"
You have the module ground
1 terminal is coil NEG
1 terminal is BAT (ignition run) along with coil+
Other two are pickup terminals.
!!!DOH!!! Here........they have a diagram........
NOTICE THERE IS NO distributor pickup---this thing is triggered by another module. This is an EFI car so it's controlled by the engine control module, it's just that the coil driver stuff is external rather than inside the EFI module No idea what "that trigger" signal is
Edit try again........
