Darren,
Yes, Shoebox is in my bookmarks and I use the site quite a bit. I used their harness picture when I was sorting out mine. Thanks for reminding me.
Sanchez,
I'm not using the stock fuse box (didn't get all the pieces) and my harness is from a 1995 Caprice. What circuits are in the C100 connector? If you can show me a close-up of that connector, I will look in my box of wiring that I removed from my harness.
LT1: if you look at the Snapshots above you will see the C100 connector wiring for 1994.(2nd Box)
The C100 is the 10 pin connector that Darren says is needed. In the last snapshot it is shown in the small circle.
In the 1994 pinout above all with the exception of pins D & E can be used
Necessary circuits to get car running:
Pins A & K from Injector feed fuses
Pin G from Ignition fuse
Pin D from PCM fuse to PCM
The other circuits for the AC compressor and Fan controls I can choose to use the integrated circuits or go Standalone with the Jaguar circuitry.
So either way I will still need to find a connector.
I will post a pic of my harness later today.
Here is a photo of the connector located in Harness about 15 inches from the PCM connectors. The cut wires are Pins B,D & E. The only one I may have to repair is Pin B if I choose to use the PCM to control the AC function. C100

Reason: add info
Way back when i built my LT1 powered car, I considered their harness. I suspect they are a market for the GM connectors.
My harness from another now retired wire guy uses two generic boxes, paired for the fuses. I mounted mine on the wing brace. With the OBD pug alongside.
My PCM is suspended on a cradle I made from the wing wall braces. i just had to make that finned alloy visible..
My relays are on a rack that I made to replace the jaguar rack on the bulk head. And a ground busss bar alongside.l
I had to replace a few of the connector housings when I did my swap due to the retaining clips broken etc, i asked around and was told best place to find that stuff was www.eficonnection.com
they had everything I needed!!
@ Carl: Painless Wiring #764-60502 for the LT1 motor is $700. That will be my last resort.
The engine/tranny/harness was pulled from a running car. The PO was swapping it out for a LS3 motor and tranny.
The C 100 Harness goes from the main harness to inside the car I guess he needed it for his swap so I am left without it
@Darren: I will at eficonnection.com to see what they have.
@LT1: I appreciate the offer.
Sorry Sanchez, looked in all my left-over parts and pieces and don't come up with anything that looks like the C100 connector. If that harness goes inside the car I know I didn't get one.
I was going to spend the big bucks for the Painless harness as my original was pretty grungy. I called them after I read something in their warrantee section. Seems they will only guarantee their harness if you used the exact same sensors (brand and part number) they use when they build them. Unreasonable! Cleaned up my old one and am happy with it.
Sanchez, the c100 doesn’t go inside that’s the 3 smaller, white, blue and black ones, c 100 goes across the engine bay to the main engine compartment fuse and relay block , I will see if I have a good picture.
I was suggesting them as a source for the connectors. Not the entire harness. I forgot what the one I bought cost. it was not cheap. and it caused me a lot of pain! it was not Painless product.
Not sure what you mean, a picture of mine? Or where the wires go? The very first picture in this thread is the c100, every single wire in it goes over to the fuse / relay center, also if you open that first picture up in shoebox, down at the very bottom are ( hard to see) clickable links to all the other connectors.
A picture of mine wouldn’t do you any good as all you can see is the connector, then. Black loom over to. Fuse block, if I am missing something let me know
No problem. Using SHBOX I will figure it out. I ordered the C100 mating connector and terminals from EFIConnections. I will make up the 10 pin connector over the weekend.
Update:
Engine Bay prepped to receive LT1. Engine Bay Prepped
I installed the LT1 today using the kit from Jaguar Specialities. LT1 installed
I will be stripping the harness next week to start wiring the LT1.
Andrew is walking me through the process of eliminating the Jag EFI harness from front to rear and other circuits I will not need.
If you run into any wiring issues join ltxtech, there’s a guy over there, injuneer, he’s their version of our Doug, his name is Fred, not only will he help to no end, but if you send him data logs, he will also tell you how car is running and what needs to be addressed!
he’s a great guy and a great resource!
Also, if you don’t have it already, download scan9495, it’s free, and you can watch everything going on in pcm, read trouble codes etc, but you will need the obd1to usb cable! If you are going to be tuning it yourself, then I also suggest tunerpro to edit you tune, and eehack to upload the new tunes. All the above listed programs are free!
Thats all I can think of to help right now, will post more as I remember it, there is another program to upload tunes that’s supposed to be safer and if anything happens it doesn’t turn the pcm into a brick, it simply picks up where it left off, but cannot think of name of it, it’s on my laptop, but I’m at beach for the weekend, (in the jag😊 ) so cannot go look.
