hope everything is alright with your folks .have been following your thread since it started and have enjoyed it .with regards to learning about tuning , the HP tuners forum has all kinds of threads on setting up the different charts that run a modern computer controlled engine .it is a lot of free info , no matter what system you are using .
I should be back working on the harness this weekend as my Dad is back home but weak so we need to give him some help and i need to work on my 86 SE that i am driving but then back on this harness i figure a few days worth of work left on it

ok I am a bit confused as i have the Audi wiring schematics but i dont see where it is telling me what is a ground, signal or what if one of you can sheed a light this is the link http://www.corradov8.com/pi...204.2V8%20Wiring.pdf

Really, it's not. The schematic is showing where the different wire colors are going. For example, on the first page:
Injector 1 (N30) pin 1 white wire (ws) ties to E25 (Connection (87a, right inlet valve), in Motronic wiring harness) Pin 2 black/pink (sw/ro) ties to J220 (Motec control unit) pin E1.
yes it shows where they go on the ecu but what i need to know is on the throttle postion sensor what one is ground and wht 1 is signal and what 1 is the 5v referance as far as i can see it only shows what wires go to the tps but not what each one is but this could be i just dont understand it

It looks like the wiper is pin 3. The rest would be a best guess for me... blk/wht appears to be the positive line. blk/brn appears to be the ground side.
But, that's just a logical guess...
Any chance to power it and see which is the reference signal?
It is a track style wiring diagram. Do a google search on how to read track style wiring diagrams and you'll find it much easier. In short, all wiring colors are the same for all models in the same genre for their specific circuits. All grounds are brown and not black. You are missing a lot of needed info. When I wired up my VR6 and TDI Fieros, I had to get the power and ground charts, powertrain management, auto trans, and starting and charging to find all the needed wiring. Audi/VW normally doesn't have a pcm pinout chart. Once you become familiar with this style, you will find them very easy to read and understand.
Wow i final did a bit of work on the ignition i got all the coils paired up for wated spark 1&6 5&3 4&7 8&2 now i just need to solder them to spark out put's A,B,C&D

i got a chance today to do some more work on the harness so i did some splicing soldering of the igition out put now the coils should be set i allso did the MAT sensor i hope i dont get called in tomorrow on my day off so i can do more
Harness is in the car now but it needs neatend up and i need to get a GM oil sender for it i allso need to do a second o2 for it and get the knock sensor parts
I have a ? do you think the O2 would work in the center of a H pipe
The O2 needs to be close to the engine so it gets hot enough and needs to have enough exhaust flow past it to read accurately. You'd be better off putting it in the manifold.
my other thought is to use this crossover pipe this would make it so i only need 1 O2 and it will be close enough to the manifolds pluse i will be using a heated O2
Hang in there Engine Man! You've come too far to let a little cold weather get you down! I keep watching your thread eagerly waiting for the video clip of the engine firing up for the first time.... I'm sure it will be glorious!
well just sitting and watching it snow out thinking well i only have about 3 more months before i can start working on the car again and i should be able to have enough money to finish her up this spring so i can drive it and have some fun
