5 Wire MAF Wiring Help
#1
![Default](https://ls1tech.com/forums/images/icons/icon1.gif)
Im trouble shooting my conversion which is and LY6 with LS7 harness and E38 ECM. The MAF is from a 2007 6.0 truck. Im getting trouble code P0102 MAF Low Circuit. I have researched the pin assignments and I get a discrepancy for the location of the black (GND) and the pink (+12). Voltages were taken key on, engine off.
Do the wires need to be swapped?
If they do, how do I release the wires from the connector?
Thanks.

Looks like power and ground are swapped...
Looking at the connector in this photo, A is on the right and it moves to E on the far left: http://www.lsxtune.com/shop/product_...roducts_id/986
A- Maf signal wire
B- +12 ignition
C- ground
D- IAT output to PCM
E- +5 sensor power
To remove the terminals, if you have a purple TPA on the back (looks like a thin purple comb) it needs to come off first, but I can't see for sure if you have one or not in the pic. Then the purple terminal lock in the front needs to come off. Next you insert something tiny into the removal slot while gently pulling on the wire. The small (thin) removal tools on this page are an example: http://www.lsxtune.com/shop/index.php/cPath/111_113
