Go to the Speed Inc site. They carry the 3 bar map and the wiring pigtail to plug it into the factory harness.

You cut and rewire it.....if you go with the FAST 3 Bar they give you a male plug that you have to pin. You can get the pins at radio shack....or just get the FAST adapter harness....which ever works....just one costs more....

Just use a small paper clip to depin the stock MAP connector and transfer them to the new connector body. No cutting needed
