Pa75vette did a great job in explaining until a point. I’m gonna try to show what’s next:
So as already explained SIDE A is where the ETM cable’s are, which is what i have in picture.
In order to slide the connector out of the “white” ECU compartiment you gotta remove that red volvo tap shown on a previous post. Slide that and then you’ll find connectors
1 Blue-Red A:36
2 Green-Orange A:19
3 White A:59
4 Green A:35
5 Brown A:20
6 Green-Black A:1
most of the cables are located in corners so making a mistake would be hard.
now in order to be able to depin, you gotta remove the black box surrounding the connectors, in order to do so, you gotta depress the pink latch to the side that moves (cant remember now) and you’ll end up with this:
once you get here, you’ll see on the above picture a large pink plastic thingy. This you need to either remove or lift in order to be able to press with a “needle” or anything you have handy to be able to depin. Remember not to push the cable until you press on the pin’s tab and then push. It goes in 2 steps, you’ll know what i mean once you’re looking at it.
To remove pin #1, you’ll lift the pink on the outter side (top side of the picture), but to get access to pin 20, you’ll have to separate the connector and reach to the hole from the inside to be able to release the cable. This was let’s say the hardest one to do bc it took me a while to figure how to separate the red/black connectors.
pins 35 and 36 were a paaaain to get out (they are located on the center on the other end) and the only reason why this was hard is bc i didnt buy the $50 depinner tool that napa wanted to sell me (i live in yukon, canada btw, might be cheaper for you) so it took me a while to create my own tool and after a long time finding something thin and long enough, i could do it. This pins work different bc you gotta press both sides of the pin in order to be able to remove it.
Wish i things i had or knew before doing this;
A better magnifier. Please get one, and ideally the kind you dont need to hold with one hand.
And a depinner.
Another thing to note and maybe encourage DYIers.
I’m not a mechanic or mechanic friendly, I did all this due of lack of mechanics in town, needless volvo specialists and bc I’m broke.
It took me time and patience but it’s 100% doable for anyone. I’d recommend also being delicate in this area, but maybe this obvious for most.
Reassembling was easy, remember to lock to the END the 2 pink latches from the TCM and ECU otherwise it doesnt fully connect.
Then my new harness was taking more space on the hole made for the cables to get in to compartiment, so my box doesn’t fully close on that end. What I did is cover it with electric tape so no water gets in but at this point I’m sure you’ll all have your ideas to how to finish the job.
connecting the other end was super easy and i didnt remove anything, just unpluggged it and plugged new one. I do have small hands btw. Might be different for others.
Ok, hope this helps anyone there with the same problem. Cheers!! (i’ll add some extra pics now)
