Hi
SirJag sent me a PM requesting a flow chart for the injector wiring harnesses ( a testing procedure printout).

I found this information in JTIS21 1999 XJ Powertrain: 303-04 Fuel Charging and Controls section - Diagnostics & Testing - Fuel Charging & Control - Pinpoint Tests.

Here is a PDF file I created:

XJ (X308) Fuel Injecor Circuit Pinpoint Tests.pdf

Also I extracted 2 pages from the 2001 XJ Electrical Guide that has the Fuel injectors circuits:

Pages from jzj2001en.pdf

Note that the Pinpoint Tests mentions Fuel Injector Electrical Connector P107 thru P114. It seems that the Electrical Guide lists them as P17 (P107), P18 (P108), P19 (P109), then P110, P111, P112, P113, P114.

I am not sure why this is so, my assumptions are in ( ).

Increase PDF reader page viewing to 150% (to be able to view small text).
