my car is and has been built fairly well, and does run, by someone, at sometime was great i guess, but i don't have any clue on who they were, or what they did...all i have is the car, and im trying to reverse engineer what they did.
afaik, they had a similar device like the war chip (if not an earlier version) and kept it when they sold the car.
the car came with evidence of a 3" tb, and a different intake, as it wouldn't even idle, and they just left a stock intake MAF just hanging in the engine bay...clearly there was another setup prior to my getting it...but anyways.
...onto the reason for the post.
reading page 9 in the directions (https://www.millerperformancecars.com/files/Manuals/PSIK%20Installation%20Manual.pdf), i found my car already has a few alterations to its wiring harness...
there are a few wires already cut, and a few "Tees" into the red wire...
the cut wires are not too much of an issue b/c the car has a lot deleted (A/C, PS, cc, ww, etc...and its also a 84 323i euro with a motronic harness (that works)...so...again, im not surprised its hacked a bit.
a few quesitons...about the "T" i will be making.
what does this tee wire connection do ?
and
should i re-wire up (or get a new) wire harness for this ?
or.
can i test out the psik + war chip by simply leaving the harness ? (after learning what wire is necessary. and routing them)
note: i think i need a new harness (which i am willing to do if necessary) but wonder, if anyone has any further input before i rip it all out and start from scratch.
here is how it was when i bought it (notice about 3-5 wires sticking out of the taped up loom a few inches from the ECU they look freshly cut.
btw...clicking on a pic should open it in another tab and be able to be much larger as you click it there as well.

and yes, the rust will be dealt with in a few months when the cage goes in
