from blue/red connectors to haltech ecu? hi,
does anyone know the part number for female blue/red connectors i want to build my own adapter to make haltech work with psi harness,
i found that boomslang adapter but it cost 999 for that price i would buy new haltech harness,
i think making my own harness would cost me around 200-300 but if only i could find the connectors

im thinking i might just cut like 12inches away from the ecu and install a quick disconnect connector to swap between the blue/red connector and haltech connector,
do you guys know which connector i could get to cover the blue/red wires idk what is it 160 wire max?i know most of them are not used with psi but i dont know how many wire im using

You're looking at 130 wires MAX instead of 160. A lot less if you don't use certain things.
For example: Not having drive-by-wire, factory O2 sensors, EGR, A/C, 4-wheel drive, EVAP, 60e/80e transmission controls, OBD signal wire, or coolant level puts you down to ~60 wires.

This would be fairly involved since the Haltech has a single 5v reference and single ground reference for all the sensors the ECU supplies power/ground to. Each of the sensors has a dedicated pin for 5v and ground on the stock PCM however they are simply conjoined internally on the PCM board.
One note that not many people realize, the pins used within the stock GM connector are the same pins used in the Haltech connectors. So you can simply de-pin the wires from the stock connector and pin them into the location on the Haltech plugs you desire. But like stated before all the 5v reference wires will need to be tied together to hook up to the one pin on the Haltech plug, same with all the sensor grounds.

i think now i need to wire in,
alternator signal
reverse lockout
narrow bands
tach
speedo
flexfuel
wideband
im not sure if i have enough input and out put for all of those i think im gonna use the electric fan output for the alternator for some reason the software doesnt let me use b10 pin i think that might be because its input not an output and reverse lockout if possible to control the speed and rpm,
can i tap into one of the 12v ecu wire and connect it to the reverse lock out
and for the electric fan how do i get a ground switch i dont think i have a place to get coolant temp sensor i already used the 2nd one for a gauge
Yea I doubt there is going to be enough I/O to take care of every little creature comfort the stock PCM dealt with. We always do parallel wiring on Fbody and C5's so that the stock PCM can take care of all the junk to not waste I/O on the haltech. This way you can add all the functions you wish without adding I/O expansion box's.
