I'm still confused.
I have a Trans Plus here in my hand.
The box has 3 harnesses coming out of it.
pink/black/yellow, connector has a purple sealing ring. This connector plugs into the new MAF.
pink/black/green, this is the signal output harness.
gray/white, this is the EST (spark signal) harness. We'll hook this up last.
Now, the unit ships with some other stuff. 1: a 6 inch long adapter harness with pink/black/green wires and connectors on each end. one end has a purple-ring connector on it, the connector on the other end is a little bigger. 2: a 18" gray/white connection pigtail, connector on one end. 3: a jumper plug (small plug with a wire connecting the two pins).
So, once we have identified all this.
Get the 6" adapter harness and plug it into the pink/black/green harness on the trans plus.
The pink/black/yellow harness on the trans plus plugs into the new MAF.
The big connector on the 6" adapter harness gets the vehicle harness plug that used to go to the old/stock MAF.
Open the Trans Plus, (4 screws in the cover)
Set the switches as follows: On On On Off
Set the dials as follows:
3" MAF: 3 0 0 0
3.5" MAF: 0 0 0 0
Get this stuff installed and running and then we will hook up the EST/spark control stuff.
