Technically this wire handles other **** but we can deal with it later if you actually give a ****. (Hatch release and Brake Shift Interlock - both can be bypassed)

C - Can't find the circuit yet but its from C220 which has the Orange/Black wire as well. Probably somewhere near the dash/firewall area. Link showing other headaches for you. Found Instrument Panel fuse block fuse 2 TURN B/U Brown wire feeds terminal C

D - Instrument Panel fuse block fuse 2 TURN B/U Brown wire feeds terminal C and terminal D goes to the reverse lights through connector 400. C powers D my man.

E - Underhood fuse block 2 STRTR mini fuse 15amp has the purple/white coming out. The clutch safety switch has the purple/white wire which feeds terminal E and....

F - the Dark Green wire is the other one which feeds the Starter Relay coil side I believe. Other wire is Yellow/Black on the relay which should be for VATS ground signal from BCM which I assume you can ground as well as some other rewiring if you want to bypass vats. Found the last diagram I needed so some of the pieces didn't fall in till the end. Let me know if you need clarification etc

A- Just grounded, easy enough.

B- The C220 connector has 2 blk/org wires. 1 of which is for the NSS(Pin H) according to posted Pin out. Pin 34 on the blue PCM connector is the noted as a blk/org wire for the NSS as well. Im going to assume that wire goes from Pin 34 on the PCM directly to pin H on C220. So i will snip wrie and fix new wire to the blk/org from pin B of the shifter plug, yes ?

C-The second blk/org wire out of the C220 is pin F. This is labeled as "UART Serial Data" on the pin out sheet. I dont know what this means. Do i run pin C of the shifter plug to pin F of the C220? Or do i run it directly to the brown wire off fuse 2 of the interior fuse block "TURN B/U" which im assuming is Turn signal and Back up lamp

D- brown wire off "TURN B/U" feeds pin C and pin D goes to reverse lights threw connector 400. What is connector 400? and C powers D? Does the wire that runs into pin C also provide power to pin D? so when the shifter goes to the reverse position, it completes the circuit and signal is sent to the "turn B/u" fuse? Do i just run a wire from pin C to the brown wire?

E- Run this wire to the purple/white wire coming off the "STRTR" 15 am fuse on the fuse block under the hood? or can i just connect it to the purple/white wire by the pedals for the M6 NSS?

F-This one confused me a ton as well. "you can ground as well as some other wiring" So do i run this to a chassis ground? the C220 connector has a grey wire off it for the CCP singal. Which im assuming is the same grey wire that goes into the 2 pin connector for the M6 Clutch switch. Do i just run the wire for pin F to the existing grey wire for the Clutch switch?






DISCLAIMER: all of the above may be in correct. I am no expert at wiring, but it made sense to me.


DISCLAIMER 2: I am not an artist, im sorry for my poor drawings. But here they are. 2 versions. both pretty much the same.

A -

B - Don't snip, T into this one. It hooks into the hatch release and brake interlock etc. But ya, sounds like you got this one.

C - Brown wire from the fuse labeled TURN B/U (Back Up) feeds pin C. Hook C up to the fuse, not the other wire.

D - Run the Light Green wire from the shifter to the reverse lights Light Green wire. Connector C400 is a 6 pin connector near the driver rear tail light. It feeds the rear lighting. Obviously the reverse light wire is here. You can probably trace it back a bit in the car and tap into it. Got it?

E - Yeah, you can just connect it to the CSS wire.

F - Sorry I was tailing off on the idea of deleting VATS. Ignore all that and the color is Dark Green, its the other wire on the CSS. Yes, connect that wire to the shifter wire.

We good or want some ms paint brah???

A- Gunna ground

B. T into in on the engine harness side by the PCM? Or am I okay tapping into it on the Dash harness side coming out of the C220

C. Hook to fuse itself, not the wire comin off the fuse

D. run this wire to the back off the car and Find the reverse light wire. Do I T into it? Or just snip and connect

E. Got it

F. I think now you a tuner can delete VATS. Also I read it's pretty easy to bypass via resistor. So just run this wire to the grey Clutch wire by the pedals.




Right ?



Adam, thank you so much for your help. I owe you some shore point bbq blueberry ribs

[sweetbmxrider]

A - bukbuk

B - Wherever you want, just T a bisch

C - The fuggin wire, I didn't literally mean the fuse Its brown!

D - Snip it. I was saying you might be able to trace it back towards the front of the car. Don't know where it runs exactly. Up to you but the power is coming from the shifter, so SNIP IT!!!!

E - Blueberry ribs

F - Many ways around vats but part of it is pcm tuning, yes. The other part, you can do resistor or do it my way, up to you The wire should be dark green, next to the purple/white wire of the clutch safety switch. Don't know where you are seeing gray?

Iirc, the Clutch safety switch on the T56 has the blk/wht & grey wires. The NSS has the grn & purp/wht.

Did you mean NSS but said CSS? Or am I wrong

[sweetbmxrider]

Its technically called the Clutch Pedal Position switch and its Purple/White in and Dark Green out. Same colors are used for an automatic's Neutral Safety Switch. You might be looking at the clutch release switch? Or something like that, where it senses the clutch pedal is up, like a brake light switch. Orrrr something completely different!

I'll just yolo it and run pin F to the green wire next to the purp/wht and call it a day

My man

[LS1ow]

So now that we've solved the wiring... and no one has bothered us...

What you wanna talk bout?

[sweetbmxrider]

Lets see some wheeling shots!!!!

I feel like pit bike could handle that.....challenge considered!

[Blackbirdws6]

I wanted to bother you....

theres a little track up there. Pretty cool area too. right on the border of NY and NJ.

Sometimes these threads need to be productive. I would have told you to buy something.

I'm basically saying hold off and get the car up and running. We can always re-ruin it later.

How do you plan on wiring in a fire extinguishing system?

so your saying i should opt for the cheaper headers...

Just get the ones that go out the top of the hood or towards the rear of the car.
