OK then it's not the reverse switch (yet). I'm not terribly familiar with what fuses do what in an XF but the reverse lamp circuit should get supply from the ignition. So if you check for supply at the fuse with ignition on, that would narrow it down more.

There should be a connector in the engine bay coming off the main loom that goes down to the box for all the devices on there (speedo, reverse, neutral). That one you bridged may well be for a neutral switch which if fitted, lives in the shifter housing on the old 4 speed. That tells the computer to do certain things with timing, etc when in neutral.

i don't remember the colour code of the wires, but the other 2 in that plug need to be joined or the car won't start.  (other than the 3 for the speedo)
 

if the lights aren't working, you'd just have to start checking fuses, globes themselves, the earth for the tail lights. 

I checked power at the back of the globes and there wasn't any power there either, the globes are perfectly fine

Did they come on when you bridged them like Dean said? That would be the first bit of diagnosis to do before diving into anything else.

No, it was already bridged or twisted together and they still don't work and have no power at the wires

yeah, if you joined them together the lights would come on if you wanted to test them  prior

Today when I was underneath i noticed 2 wires joined together long enough to reach the switch but the reverse lights still don't work and i wasn't getting power at the ends of those either

if you follow the speedo cable wires to the plug near the firewall, there should be in the same plug(rectangle plug with 7 wires of an 8 hole plug i think)

3 are for speedo(you followed this from the sender on the gearbox)

2 should be looped (this is the starter wire inhibitor if it was auto)

and the other 2 are reverse lights, they should reach the T5 switch from memory 

ill have to take a look tomorrow but those 2 reverse light wires both got to either side of the switch?

So I recently bought an XF sedan that's been 5-speed converted it was originally 4-speed manual and the reverse switch hasn't got anything plugged on to it and I'm wondering where the wires would be located to solve this issue, eg what colors were the original 4-speed reverse light switch wired too?

Thanks everyone for the help found the issue there was a break in the wire and we hookes the power from relay to the plug and it ran perfectly, untill i found out the thermostat is corroded

Red and green wore coming from this relay 

Red/ green wire to ignition coil but have power at coil but dont know if in coil

Got no power at this plug either this plug connects to the whole injector loom 

Looked at the relay and when begining to crank over it clicked and the fuse in the pink housing is fine but cant see if the wire goes to the injectors as it is within the wireloom itself but it seems it goes to the area near the injectors and possibly plug 

Where would the power for the injectors come from? Would it be the Ignition module at the dizzy

Investigators want to know why you changed pushrods

I changed the pushrods because two were bent

that black relay has a wire intercepting it, was it on LPG? 
might be switched for LPG. did you delete any wiring?

It did run on lpg before i had it but we removed some of the lpg involved things except the wiring it ran fine till after taking out the injectors and changing the push rods and putting them back in and it hasnt started since

the only thing i can think of is the green and other relay near the brake booster,(green is fuel pump, other is injectors i thought? could be wrong)

 

haven't broken an earth wire or left a plug loose?

Haven't got any green relays only a got a grey wehrle relay with fuel written on it a white ford one and a black ford one

did you unplug the ecu box inside the passenger feet panel

No, I haven't

Hey Guys,

Recently I have replaced the push rods in my 250 and had to take out injectors ect.. it started before beginning the process and now it doesn't could it be a fuse? because i've tested the power at injectors and there is no power there. what could cause the injectors to not get power or the engine to not start?

Thanks in advance
