Td5 Main harness to RH wing harness

Hello all,

I'm currently part the way through replacing my two front wing wiring looms. The O/S side it relatively easy to replace without removing the wing entirely - the passenger side however, is made harder by a duct being largely in the way [scratchy head, think]
Progress was going well until I came against the 'C1266 - grey female' connector, adjacent the heater assembly, clipped up to the bulkhead...does anyone know how you separate it - is there a particular knack to it. I've pushed the leaver down to release the clip part of it, but its still not budging

The female connector (main harness) is clipped to the mounting bracket and won't move unless you unclip it.




Make sure that the release clip is free from dirt, which can stop it depressing fully -




Once clean, depress the release clip at its end, while firmly gripping the male connector (wing harness),
and pull/wiggle it out of the female connector -




.

Thank you very much Paul!!!

I didn't know about this clip. What action is it: slidy, unpick, push; and what tools are handy to do this?

I will have another attempt at it this weekend.

This female connector is shown in the same orientation as the one on your main harness.

I've fixed a body mounting clip (the black shadow!) into it - the connector slides-up onto it -





In this picture, I've flipped the connector over, so that you can see the retaining latch for the body mounting clip.

The grey retaining clip should be pushed in the direction of the red arrow, whilst pulling the connector off of the mounting -





So, for your connector, you will have to reach underneath the connector, push the grey retaining clip towards the bulkhead, and the connector should slide-down off of the mounting bracket.

Yes! Amazing Paul, thank you; that has worked a treat! Your diagrams are SO helpful. It was such an awkward angle to look in at and see what I was trying to do.

further discussion:

I've now managed to feed a new loom on the drivers side, but the passenger side I think is going to have to be a whole wing off jobby . [hgfc]
I've got treadplates bolted through the wing (that two of them have seized...obviously ,) and the duct has been screwed to the inside of the fender . Just feeding it through the inner & outer and back up tot the bulkhead again is going to be tricky, I've also got to get to the lower bulkhead to work out wiring to the passenger door as the electric window has stopped working (I suspect a loose connection again) as I did replace the motor regulator mechanism - and wiring through the door grommet it very tight; that, or a burnt out terminal somewhere

While re-looming gives piece of mind agenised previous bad splices or dodgy heat shrink butt connections etc etc... if it doesn't solve flickering and headlights working when they want to work and not when they need to - what is next to explore? They are : TP LTE LED headlamps.

Is this simply down to a bad earth somewhere (engine-bay bulkhead)? Or current flow; the variation from halogen to LED? Should I be looking to remove or by-pass the resistors in the front drives wing?
[Running a full LED system now, no halogens at all]. I don't think it is the headlight switch itself - I keep replacing that also , I've also switched out the dip/dim relay, and doesn't always solve my immediate problems either
