12592525 Map Sensor Wiring With Terminator

Had a terrible time with my wiring and sensor for some reason. Even called holley tech line and got some little bad attitude prick who gave me the wrong wiring I suspect on purpose because he tried to sell me an overpriced holley brand sensor numerous times promising it to be plug and play. Hope this helps someone.

Where did you plug in the gm sensor on the intake manifold?

Same problem the black one will make your 5v reference go down and it will no cranck bc will affect the 5v reference on cam and crankshaft so will not cranck disconnect the sensor and check for voltage and u will see i will have 5v again so idk it acts like a short group when u have that black map sensor conector

The red sensor is a ls9/LSA 3 bar sensor, the black one is an ls3 “1290” 1 bar sensor.
