OBS chevy LSx wiring

[NITROUS]

I extended my wires and put the pcm on the passenger side and put my relays and fuses on the drivers side. Pretty much all plug and play.

The small cover on the right houses both LS1 fan relays and the cover on the right houses an extra fuel pump relay, extra A/C relay, fan 1 and fan 2 30 amp fuses, an extra 10 amp fan fuse, an extra 20 amp fuel pump fuse, a 10 amp PCM battery fuse, a 15 amp A/C fuse, an extra 15 amp pcm ignition fuse, and 3 extra fuses for fuel injection if needed. I made the small plug and play harness with exra features to use in other vehicles.

The gas gauge is standalone from the PCM so the sender is hooked up just like factory.

Nice relay/fuse centers. And where did we source these from?

Very nice, can't wait to get mine started.

on the 98 it uses the pcm for the gasgauge

[NITROUS]

beater6.0, your talking about the purple wire pin 9 on the blue connector right? I don't know why it's needed to be honest unless the sending unit has changed in 98. It's not used on 96-97 and I have a set of 98 and 2000 tahoe gauges that both work in my truck without that wire. Let me browse through the factory manual and see why you would need it.

[NITROUS]

What I see is that the purple wire goes from the VCM (Fuel gauge level) through the C100 to the cluster (fuel gauge). I'm not sure why you would need this because the diagram shows the purple wire to go to an external fuel gauge and from there to the cluster. I really don't think you need this wire from the looks of the schematic but I could be wrong.

its been awhile but itried bypassing the pcm but noting happened but at the same time sendingunit went out so going to worry about another day
