Hello I was hoping someone could point me in the right direction to find a wiring diagram for this car, the tail lights and blinker harness looks like a butcher got at it, same as front headlights and signals, i got brake lights and rear signals working, but i cant get the marker lights/ day time running llights to work ? also cannot find where to wire the reverse lights up to, i got front high and low beams working but cant get lower marker lights to work. the side signals how ever are working. any help is appreciated

 

Are the bulbs good?

 

all bulbs are good

 

Do a Google search for "coolcat jaguar electrical diagram" and that may bring up the PDF. I looked on Mike's site but couldn't find t h e link. However, the best next purchase for you is the Bentley publ. Co Jaguar workshop manual. EVERYTHING you may need to know is there.
this is what it looks like, better price is probably available.

I recalled seeing a number of good wiring diagrams online, but now many seem to have disappeared.
I did find one here that seems pretty decent: XKE Data - Resources - Jaguar E-Type (XKE) information, articles, photos and register
I converted it to pdf - it's attached.
It's sized for 8-1/2" x 11" but the resolution is high enough that you can zoom in on a screen or upsize to a larger print format.

I'm intrigued by this one: https://www.welshent.com/Fitment/Lit...III-V12-E-Type
It's tempting to spend the $14 just to find out what it contains. But shipping would cost more than the product, so it'll have to wait.
