Hello All,

I'm putting LPG in my 1998 4.6 HSE, and this afternoon I was soldering in the gas injector loom.

To do this you cut the negative wire from each petrol injector and solder in wires to and from the LPG ECU. This allows the LPG ECU to know when the petrol injectors are firing.

Thing is the electrical troubleshooting manual in RAVE doesn't show the correct wire colours to the correct cylinder. At least they're not as they are in my RR.

I thought the cylinder order was


FRONT
2 1
4 3
6 5
8 7
REAR

But when cutting the wires to the petrol injectors wire colours were wired up in this order...

FRONT
1 2
3 4
5 6
7 8
REAR

The engine runs fine, and of course the wire colours don't matter provided they're connected up the the correct terminal on the ECU, but has anyone noticed this before? Is this just crappy build quality, a mis-print in the manual or am I missing something?

Plenty of miss prints in RAVE

Glad I double checked then!

I'll have a look at the pin outs at the connector to the ECU and see if they're connected to the correct pins at that end. Got to be really, otherwise the engine wouldn't have run I suppose.

Good to know there might be the odd red herring in the book though. Cheers for that.

I have found the answer.

Left on the engine is left as you're sitting in the drivers seat, not as you look at the engine.

I didn't know that, I do now. It all makes sense again!

You could just have searched LZ - been explained many times like here: http://www.landyzone.co.uk/lz/f10/ht-leads-187170.html

no 1 cylinder on a "v" engine is always on the "leading" bank at the front pulley end

Yes, but I assumed I knew my left from my right!

Lesson learnt. Never assume anything, especially when it comes to V8 engines, and women.
