B&m shifter wiring, help needed please

im a little confused with the wiring for the megashifter.

Basically i have three questions


1. should i have power to more than the dark blue wire?

2. with the two switches, it dosent say where or which prongs i should attatch to first. i assumed the lower prongs go to dark blue? the directions say different then the schematic?

3. in the circled area of the schematic do i take a new wire from saftey swith to a2/1 on the relay then ground a1/0 or what?


your help is much apperciaated

1. I'm not sure about that one.

2. As far as the switches go, it doesn't matter which prong is connected to which wire, as long as the second wire on each switch goes to where it should.

3. Yes, you take a new wire from one of the switches to the coil on the relay ( in this case, that would be A2) and then another new wire from the other end of the coil (A1) to ground.

Quick question, did the B&M shifter come with a shift plate? The plate that says P, R, OD, D, 3, 2, 1.

Yes it does come with a shift plate, but you must have the original shift plate from the car to mount it to. You cut out a hole in the original plate and then screw the included plate down on top of that.
