81 gtv-6 electronic ignition
I need a wiring schematic for 81 GTV-6 electronic ignition. I have converted a 2.5 over to carbs so all I need is info on wiring for the coil to ignition unit and dist.83 might be the same,I don't know.Can anybody help? Thanks.[/b]
Lets see if we can help you out here:
If your distributor is the common inductive type, all you have to do is connect its output signal to the Bosch ignition power module under the coil. Do you have ANY Bosch ignition wiring data?
Early v6 engines had centrifugal advance distributors, some with and others without vacuum advance. These types of distributors had a small black socket, with 2 little spade contact pins inside. The plug mating with this connector is at the end of a green (most probably) coax cable. The other end of this cable goes to a flat 7-pin black connector, fitting on the ignition power module on the heatsink, underneath the coil. The plug clips on the module with a very secure clip. It clips on, but doesn't come off until you pry off the clip! This plug has 4 wires coming out: the thick green one going to the distributor, a black one going to chassis ground (usually a spade lug under the coil, on one of the module 2 screws), a white one going to the coil(-) terminal, and a green/black one going to the coil(+) terminal. This is the ignition connection. To make it work, you must find another green/black wire, coming from the vehicle harness and originating at the ign. switch, which must also be connected to the coil (+) terminal. This is the current supply for the ignition. There should be 12V there when the key is on.
This was the simple case!
If your car had the Hall-effect distributor with the relative control module as in later cars, things are more involved. You will have to retain the life support for the module in order to get sparks.
I suggest you find someone who knows their stuff to work on your car. It really is simple but too cumbersome to put in writing.
Good luck!
