Wiring Diagram

[Stu]

Anyone know where I can get a copy of the wiring diagram for an NB8B?

[Andrew]

Will an NB8A be ok

[Stu]

Thanks Andrew, for what I require the NB8A wiring diagram should do.

Thanks mate.

[Andrew]

No worries

Awesome!

I'm doing a head unit install. Any ideas whether the audio wiring diagram changed between NB8A and NB8B?

I ended up getting the radio adapter harness from Mx5parts.co.uk. It cost maybe $20, saved time and the OEM wiring harness. Mania may have this part in stock as well.

Incognito's write up also used this harness

Thanks for that, Stu.

FWIW, the NB8B has a different plug. It's a single plug with much smaller pins. I'll update with a photo tomorrow.

From what I can see (tested a few wires), the colours of the wiring is still the same, so it shouldn't be hard to figure out.

Now I just have to return the adapter and go looking for one that fits!

This is what the NB8B clip looks like.

[Stu]

It looks exactly the same as mine.

I ended up going for a stereo -> oem plug which then plugged into the oem -> mx5 cable from mx5parts. I'll try and take some shots tonight of the cabling and connectors.

Just visit your Repco/Stupid-cheap and get them to order one.

Thanks for the tips guys!

I've ordered myself a Metra 70-7903 wiring harness and Metra 99-7505 replacement fascia. $55 from America.

Now to wait for it to arrive.

BTW, local audio shop wanted $60 for the wiring harness and $50 for the replacement fascia. You try to support the local guy and you get reamed.
