MX5 Donor Electrics

Hi,

I wondered if there is anyone who might know their way round an MX5, specifically the wiring I am using on my build and a couple of missing wires I think I have.

I've got pictures etc I can post up so thought I'd ask.

Thanks

Jon

Hi,

It was a 2003 MK 2.5 I believe.

Thanks

We recommend using the donor MX-5 loom on our ANC Replicar kits - so may be able to help. All the wiring diags are available in the Haynes manual - so if you post pics of the area/system you think is missing the necessary wiring, then I should be able to identify it.

Hi,

That's great thank you. I have a few questions so will just post them up separately.

on the main battery feed from the battery about a foot away there is a connector, what is this for??

The second question is the earth cable, it connects to the body and then extends further along and I assume connects to the body els3where but am just worried it should connect to something rather than just the body.

Ref 1st question: I'm away from unit til Monday and so will check our demonstrator and Haynes manual then should you not get a reply in meantime.
Ref 2nd question:The negative cable would have gone from the battery to the Mx-5's powerplant frame (the alloy spine that connects the diff to the gearbox) using the broken - off connector in your pic - and also tee'd off to the Mx-5's body with the other connector in your pic.

Hi, that's great thank you.

Last question I hope but I think it's the dumbest one. In the pictures you can see the main fuse box and a 3 pin connector which goes into the underside. I have snipped the red wire which i am pretty sure is a feed and probably why the injectors are not firing. Can anyone tell me what it's for and also where to re-instate it from?
