Hi there!

As I am preparing my engine and tranny for a refit (which will happen next year as it looks now...) I noticed, that the rear harness, the one that connects the oil pressure sensor, reverse switch and co (I think the kickdown switch aswell!?) is extremely brittle and is cracking.

I can't find/locate the correct parts number. Is this available new or must I rebuild it? I doubt it will be a problem to rebuild, but I want to try to keep it original...

What are your opinions?

Cheers

Damien

 

Daim,

I think that's DAC1673, sadly NLA from Jaguar at present.

Damien, you can rebuild the harness yourself. Use GXL wire, which is a higher temperature automotive wire that won't go brittle.

Cut the wires from the connectors about 50mm from the connector. Cut some heatshrink tube and strip the wires about 15-20mm and solder them together.

DO NOT use electrical tape to wrap the joint, use heatshrink. Tape will eventually come off.

Here is a good video on how to join wires. I use both methods depending on the wire type, thicker wire I interlock and thinner wire I twist. I also use needle nose pliers as soon as I have soldered to lightly squeeze the solder joint, this does 2 things, 1 cools the joint quickly reducing the heat soak into the insulation, 2 removes and sharp bits that may pierce the heatshrink.

 

What would you say to updating the connectors whilst at it? I would replace the old round plug with an appropriate sized AMP superseal or even with a couple... I know some parts are just cable shoes but otherwise the rest is kind of unique plugwise...

 

If its inside the car I use a general purpose automotive connector, these are cheap and reliable if not subject to weather and dirt.

Outside I would definitely use a sealed automotive or military connector.

I replaced these a few years ago as they were full of old coolant from a leaky heater core.

 

These are all in the enginebay. So waterproofing is of course a must do...
