PM-76 PIMP Harness

Would like to use this on my 95 Mustang. I’m tired of messing with the stock harness.

Any issues? Will dash still work? (Tach, oil pressure, coolant, speedo)

Would love to dump CCRM.

I’m thinking I’ll need to do the following:
1. Source a soft start fan controller to connect to the H fan trigger.
2. Move the TFI plug to the fender. Can I relocate the TFI to the interior?
3. I have dual spartan 2s need to hard wire those.

Dash will still work.

TFI can be in the interior I guess, though it doesn't seem worthwhile.

I purchased. Thanks

PM-76 is the part number we use to differentiate between the two options, the manufacturer uses PM-75 for both and just wire the injectors according to the order option. So, if you order a PM-76, the box and invoice will say PM-75.

I have three questions after looking over the harness.

1. All grounds tie together and are to be connected to the engine. Is this acceptable? At least remove the O2 grounds?

2. Pin 4 IDM. Should I add a 22k ohm resistor to filter noise like the factory harness?
**EDIT:  I just looked, this is already done  4" from connector**

3. None of the relays have a fly back diode. Shouldn’t they with the ground setup of this harness?

If installed like outlined in the provided instructions it will function correctly, assuming your vehicle has all of the stock grounds. Obviously grounding to an engine that isn't grounded will not work, but the engine is supposed to be grounded to the chassis as it is from Ford. If you would rather ground to the battery or chassis or wherever you'd prefer, you're free to do that. When building a harness for universal chassis use, the engine is always in the same place relative to the harness, the battery and chassis ground points are not. If you want to add flyback diodes you can.

Great, thank you. I will add them in.
