Default Wiring diagram for a 1997 xk8 jaguar

I'm looking for a wiring diagram for a 1997 XK8 Jaguar. I need the pin order of the Black, Green, Blue and Lavender wires going to the throttle body.
Wires are located on the right side.

This is what I'm looking at. The manuals don't seem to have this color code or maybe I'm not looking at the proper diagram.

Colours appear to match other than lavender which I guess is the one with the spade terminal on it?



Pins (top to bottom) :

4 Blue/White
3 Blue
2 Green
1 Black/Green

Michaelh, you were 100% correct! Thank you so much. Now to scour the earth for the proper connector that doesn't cost $150!

Before I completely break this spare XK8 in my driveway I'll be sure to cut off all the oddball connectors for future community use...

According to the Electrical Guide, it's a 4-WAY SUMITOMO TS090



$10 or so on a quick search on OEM P/N
Also seems to be available in pigtail form on Amazon US

Thanks again Michael. I'm 76 and this is the first foreign car I've ever owned. It's quite a project trying to figure everything out. I've been trying all day to locate the Idle Control Valve on this 97.

If it helps, and it may be just me not getting the humor :-D but I believe the 1997 Jaguar XK8 does not have a traditional idle control valve. Instead, idle speed is controlled electronically by the drive-by-wire throttle body. The Throttle Body Module (TBM), which is integrated with the Throttle Position Sensor (TPS) and an electronic motor, regulates idle speed.

That would make it hard to find then, lol. It's just a screw on the carb on my old Chevy. I'll probably be giving people plenty of things to laugh at.

You'll be the one having the last laugh when you get that baby purring! No question is a dumb question, but I've given a lot of dumb answers in my life...

^^ Aye, all of this stuff is managed by computers.

Given the number of screws to twiddle on the semi-dual choke carburettor on the MKII Golf I can't say I'm sorry.
