Injector harness re-wire (need experts plz)

[Dropped325i]

Hello everyone i found out the following info on the harness, i want to re-do the wires that lead to the injector clip on my 325i i6, thi sis what i have for info

(7 wires)

Injectors = Red/White = goes to main relay, drivers side, left one in front of the afm..
Injectors (1,3,5) = Brown/White = goes to ECU # 16
Injectors (2,4,6) = Brown/Yellow (bigger wire) = goes to ECU #17

coolant Temp sender (ground) = Brown/Yellow (smaller gauge) to ?
coolant Temp sender = Brown/Purple = goes to gauge

Temp Sensor = Brown/Red = goes to ECU # 45 ???
Temp Sensor (ground) = Brown/Orange = goes to right shock tower?


I got a couple question marks i'm not sure where to go to, basically grounds, the temp sensor said i think to RH shock tower, bu tcan i run both grounds for (coolant sensor/sender to a body ground into my car so i can have a clean install and harness) if not where do you suggest i connect these grounds? can anyone verify if my info is correct also?

Thanks,

i'm retarded i can do a continuity test from the ground wires for the coolant temp sensor + switch i currently have to body ground or check the ecu, why didnt anyone tell me this :-?

ah, screw it i'm cutting open the engine harness :) about 75% done... instead of running new wires.. PITA

stop stealing my pics, and those rims are gone, and car is dropped.. anyways...


I'm getting there...just got done doing a head rebuild, 19lb 4 pintle injectors and m30 afm, i think i'm going to relocate the harness instead of going down by the intake just to keep it on top, hers my progress so far, and yeah the other wire taped to the fuel harness rail is a wire re-routed straight to the DME (bought the vehicle like that)

i had to cut the harness up, due to corroded wires for the fuel injection harness etc.. its not done, going to clean it all up later...
