Michigan Motorsports 24" LS MAP Sensor Adapter Harness - Connects LS1 LS2 LS7 to LS3 L99 L76 LSA LS9 ZR1 MAP Sesnors - Compatible with GM Part #12592525

Did not have to swap the pins over in the harness for the gen 4 engine on gen 3 harness, seemed to be a good length, and has been holding up well for months

Two of the wires were crossed on the harness which can cause major issues. I requested a replacement but it was denied. Don't waste your time with this.

Works great!

Have used these multiple times for turbo LS projects. Work great/Never had a problem.

Just what I needed to put a zr1 map sensor on my ls1 pigtail on my Holley Terminator system.

This was perfect for my LS swap

Make sure you check the wiring on both ends of the connectors. Wires needed to get moved over to match other end. One end went black, white, red. other end went white, black, red.

Make sure you check the wiring on these connectors. If the colors don’t match, your map sensor will not work
