As stated. I want to just ground them but the insulation isn't green which has me hesitating. Does anyone know where they're supposed to go? This is on a MK3 AAZ.
Thanks.

By my experience any brown wire in A2 & A3 cars (generally) are ground. I have no experience with AAZ though.
It looks to me like they connected to the water outlet at the side of the head so I'd be 90% sure they are ground. Easy to test - connect a test light to pos on battery and touch each of them - this MAY help tell if they should be ground or not...

Yup... they generally attach to the coolant outlet flange via a double nut.

thanks fellas, should be starting the thing up this weekend if all goes well. I'll make sure to post pics/videos.

Er, are those are on the engine side of the standard electrical plug, red with a white stripe?
If so, they're the glowplug feed. Both go to the nearest glowplug (gearbox end). I've had 2 UK AAZs, both were like this (and the wires looked identical to you pic).

the glow plug feed wires are much larger gauge than those wires are..

Why does your AAZ valve cover have studs around the edge?

This.

Well, now that I look at it again the colour is a bit unclear in the picture... at least for my feeble eyes.
If they be truely brown, they should be grounds.
If red with a white stripe, they should be the double wires used to provide power to the glow plug buss... the AAZ uses a couple of small wires in parallel rather than a single heavy wire like the 1.6, since the wires have to pass thru the pins of the big engine connector.
Oh, and Ive guessing the OP has a G60 aluminum valve cover that he's bolted down around the perimeter.
"CSI: Diesel Engines" is my favorite show. ;)

Nope, not on the 2 factory AAZs I've seen. if you follow the wiring through the plug, the 2 wires join into one larger gauge wire (also red with white stripe).

sorry, they looked brown to me..
im not used to seeing 2 glow plug wires on a 4 banger, only cars ive seen that setup on, are the 5 banger diesels..

As Vince stated, I modified the head to fit the G60 valve cover.
Thanks for the help guys. Can I safely delete these wires if I'm using Vince's pimped glowplug system? I'm thinking of bypassing the system entirely and running the glowplugs with a momentary switch mounted in the cabin.

Yup... you'll provide your own heavy-duty power feed to the glowplugs from the extra solenoid.
You can drive the extra soleniod from the original output of the glowplug fuse bolted to the firewall, or use a manual pushbutton as you mention. If you pull the glow plug fuse you've disconnected those two wires in your picture and you can tape-em-and-forget-em.

Awesome, thanks Vince
