Hello DF Goblin Family,
I am looking for some help with questions I have as I work on the wiring harness. I don't have much mechanic or electrical experience so most of this is very new to me and a bit daunting.
My donor is a 2006 2.4L SS/NA Auto with ABS
Questions:
#1 I am looking at labeling the body to dash connectors and have a few discrepancies from the labels linked to the videos which is making me nervous. Below is a diagram of the wiring of my body to dash connector. It is organized by pin location and shows the color of wire, what it connects to on the main/body harness, and what it connects to on the dash harness. The connections in red are the ones that are indicated by the base labeling sheet to preserve and extend. The connections in blue are ones that I think should be preserved and extended. Some of the wires from the body to dash connector go to three connectors that I'm not sure of where they plug into. One is a 5-pin connector located near the radio, the other two are 2-pin connectors that are in the same bundle that go to the pedal box.
Here are the things I need to clarify before I start cutting wires:
a) The connection at B10 appears to be for the Radio, not the Key Lock Actuator. Is there a different connection I should be looking at for this?
b) The connection at D4 appears to be tied to the brake lights, not the OBDII power. It looks like the OBDII power is coming from D3 which also powers the front acc plug. I assume I should keep the connection at D4 for the brakes?
c) Should I keep the connection at C3 for the brake pedal?
d) Should I keep the connection at D8 for the gear selector?
e) Do I need to keep any of the connections from B6 and B9, or from B5 and F6 BCM, the two unknown 2-pin connectors by the pedal box?
f) Do I need to keep any of the connections to the unknown 5-pin connector by the radio (I am assuming no)? The connections are: A4 body/dash connector, B12 body/dash connector, black ground, pink F5 BCM, and purple 71 BCM)
g) Are there any other things I should be concerned with or aware of?
#2 Is this the engine harness connector? (wiring harness video part 4 @ 3:04)This picture is the connector on the main harness that I am assuming is the engine harness connector. I'm just confused as mine is much smaller than the one shown in the videos. The tan & tan/black twisted wire are the data wires, the green is the back-up lamp and the brown connects to B5 on the red BCM multiplug, then to position 18 on the ECM.
#3 I don't have a coolant level sensor (or at least I don't think I do). Is that normal on some models? (wiring harness video part 4 @ 2:06)
#4 Is the light blue wire that is wrapped separately, the center brake light wire? (wiring harness video part 4 @ 3:18)
#5 I don't have a vacuum sensor connector (wiring harness video part 2 @ 1:48) Is this normal on cobalts with ABS?
#6 I just wanted to verify I did this correctly as my EBCM connector is different from the videos.
#1 is a large red w/ black stripe wire that connects to position B1 on the smaller rectangular light gray multi-plug in the main fuse box. (i removed it)
#2 is a pink wire that connects to position B2 on the dark gray square multi plug in the main fuse box (i believe this can be used to power the intercooler which i don't need so i removed it).
#3 is a gray (or maybe light blue) wire that connects to position F4 on the gray multi-plug then to position 7 on the ECM connector. should I remove?
#6 and 7 are tan and tan w/ black stripe twisted wires that connect to position C5 & C6 on the Dash connector.
#4 and 5 are tan and tan w/ black stripe twisted wires that connect to the connector I mentioned in question #2.
The second image below shows what I plan to do with the twisted wires, is this correct?
