I think in the process of hacking out the crap from my harness I trimmed this pin. Where does this wire go to?
I know according to the diagram its supposed to get "Constant computer power, route to BAT 1 10A fuse" but where is the other end of the wire at? ECM plug? if so which pin.

Thanks

PS this is 02 WS6 harness.

Which schematic are you using? C100 pin G should be hot in run and start, not battery constant.

Anyway, it goes to Pin E of C1 on the transmission, it ends up somewhere else too, but I can`t figure out where. I don`t have all of the power distribution schematics.

Im actually using the 99-02 wiring doc you have posted in the faq
https://ls1tech.com/forums/3859121-post13.html


But now that you mention it, as I look at the other FAQ posts it looks like it goes to
"G PNK Hot with IGN 1 Relay Engaged (Tranny/EGR 15A) "
Sweet, I can track it down and get everything connected.

If it's battery hot, it should be feeding pins 57 and 20 on pcm connector C1.

well I went down and checked continuity

I got 4 pink wires from C100/101/105

C100 pin G is cut, but
ECU has continuity with pink ECM pin 19 (I checked pin 57 for continuity with orange wire and thats fine)
Trans plug pink has continuity
O2/Maf pink has continuity
and I checked pink wires on both plugs on the valve covers and they both had continuity.

So did I skip checking something or is that all the power needed?

Well from the diagram I just downloaded it appears that C100 pin G supplies power to the trans and the EVAP vent and purge solenoid.

I re-downloaded my how to from the FAQ and I get

Connector C100
A. This is the power for the odd fuel injectors, route it to IGN 1 15A fuse
B. Not needed
C. Not needed
D. Not needed
E. Not needed
F. Not used
G. Engine control power, route to IGN 3 15A fuse

not that it goes to a BAT fuse

SirWarrior

You're right. Looks like I cut/pasted the G from C101 plug. DOH!

But I still think I got this all fucked up.
Trans has two 2wire plugs? or is that wrong too?

Also, C220 Plug, can you give me the colors that supposed to be there for the pins A, B, C, G, K.

SirWarrior

PS Nevermind on the C220 stuff.
This post confirmed my labeling/wire colors.

But still wondering about the trans plug deal.

The trans should have a 2 wire plug for the VSS and a round multipin plug (probably 15 pins) for the rest of the transmission controls.

I don`t remember the C220 colors offhand, let me see if I can dig them up though.

SirWarrior

On mine there are few seperate plugs it seems like, I just crawled under and checked.
T56 BTW.

I was thinking an auto.
T56 would have the 2 pin VSS, 2 pin reverse lockout, and a 2 pin skip shift plug.

skip shift is pink and gray

reverse lockout = pink and light green

VSS = light green/blk and purple/white

SirWarrior

OK, yeah. Two 2pin white plug and one smaller black plug.
So those have power too, Good.
Thanks.
I owe you a beer once I get this thing on a road.
