Premier Wiring Loom

Hi All.

 

I've got a 2B with what seems to be the original loom off of the Sierra donor car.

 

It has the original fuse box and a mass of wires inside.

 

I've recently got a new loom from Premier Wiring looms I've followed the instructions to try and mark out what goes where but theres a few bits and bobs I'm not sure on.

 

How does it connect to the ECU?

 

How does it connect to the original Sierra Dash?

 

Any help on re-wiring the car would be really apreciated as I'm struggling to see where to even start at the moment.

 

Would I be better ripping everything out and starting from scratch? do i need to retain the original fuse box/ relay holder or do I just get a new box that I can fit all the new fuse boxes and relay holders just to keep them tidy?

 

Thanks in advance

Hi Johny

I had a similar issue with my 2B, decided to bin the sierra loom and get a custom one to go with my megajolt and digi dash. I now have loads of new wires to try and connect together but at least I have wireing diagrams. Still a pretty daunting task if you dont know much about electrics like me. But as I have read in some other posts, the old loom may have hidden issues that a new loom wouldnt. Personally I would go for new loom then you know its right.

Yeah I've got the new loom sitting in the garage waiting to be installed but I'm ever so slightly clueless haha.. If I had a propped wiring diagram with colour codes etc it wouldn't be an issue but looking at the instructions with the loom I can't even identify some of the Spurs from they're description etc

Hi Johny,

 

i recently started my wiring, with a premier loom, but i did not even attempt to utilise the sierra loom, i think it is more hassle than its worth. with the premier loom i purchased you do not use the sierra fuses, you may have 2 fuse boxes on the premier loom, these are usually sufficient! if you don't have these fuse boxes, I'm not 100% how to part connect in the sierra loom!

 

as for the ecu, i think the wires are on the engine loom section, this is the next it I'm going to do, but almost sure i read it.

 

as for the dash, i have used new dials and so not 100% sure on how to attach to the original sierra dash!

 

good luck and keep at it, i have so far spent many days getting my wiring sorted but there is a sense of satisfaction once done!!!

Yeah I have 2 fuse holders with 4 fuses in each and 4 relay holders. Let me know how you get on with the Ecu wiring off of the engine spur.. I'll be ripping out the Sierra loom and only using the premier loom but I was too scared to just remove the old loom as I thought it might point me in the right direction for fitting the new loom but so far it has only confused me more
