Hi,
I have an L92/LS3 with modified harness I bought from a member here. I'm preparing to start the engine for the first time and need some help on what relays and fuses I need. It appears I have everything except what would have been part of the OEM underhood fuse block.
I'm a real beginner with electrics but looking for guidance on what to do in terms of ignition, fuel pump, powertrain relays & associated fuses.
The unconnected wires I have coming from the PCM are labelled as below:
12 V+ feed to fuel pump
Battery & Fuse @ 20 amps
Starter feed from neutral safety switch (purple)
Engine harness 12 V+ key on fuse @ 25 amps (pink)
Unlabelled wire grouped with above wire (orange)
Two of the above wires are already on a relay. (grey and pink). And that is not the engine harness wire.
I have an areomotive stealth tank that came with a wiring kit that included an extra relay so I assume only a single relay for the fuel pump is required?
There is also:
Fan 1 relay control
Fan 2 relay control
Tach
Speedo
Tap shift module control for auto trans
Brake light switch
Check engine light
OBD2 port
Any help would be much appreciated.
