NA8 engine bay question

Postby emily_mx5 » Thu Jun 13, 2013 10:52 pm

Hi guys, I know the NA6 engine bay and components like the back of my hand, but in my new NA8 there are new additions that i dont recognise. these 3 relays, and a large orange plug, that is unplugged :shock:
(1995 aus delivered NA8 with an NB8A engine if that helps)

what are they? :lol:
thanks :)

Relays look aftermarket. Will try and get out to the shed to take a look at the plug.

Here is a photo of my stock NA8 (no power steer). Sorry for the low lighting - my apartment garage is pretty dingy.

You're right; your three relays are definitely new additions. I have two relays which plug directly into the large orange plug. The same end of the plug is also wired to the driver side thermo fan and a sensor on a metal line (air con/cooling?) under the intake manifold. The opposite end of the orange plug connects below to a main wiring loom which also runs to the driver side headlight and indicator. Sorry I'm no auto electrician, but I hope this helps a little.

Thanks so much for those details, I will investigate where my wires run to tonight.

These look like like A/C and fan relays on my NB.

Em, I don't have those three relays in my '93 NA8.

Smacca, I did know what those two relays were (could be what Lokiel says), but mine doesn't have them, then again mine doesn't have AC.

Ah, mine does have air con so that's probably it then. Like Lokiel said, one for the air con, the other for the fans.

Big plug is for headlights/retractor motors, I'd say they have rewired the headlights and added the relays.
NC Roadie, NC Racey, ND Racey….and a 30AE

Plus several others in the bone yard...
