So, I have the majority of the interior out of the $1400 Euro-S (See other thread if unfamiliar: http://forums.rennlist.com/rennforum...-now-what.html)

Basically going through and cleaning every piece before I begin re-placing it in the car. I figured this would be a good time to get a stereo working.

The PO seems like he pulled everything in a hurry. Didnt leave the "cage" in the dash and cut the wires heading back to where I assume the amp was?

I have the head unit hooked up to what I suspect is the original power, ground, and remote line and that works well. The problem is I cannot trace any of the lines as lines to the speakers.

In the same loom as the power and gound there are 6 other wires: a positive and negative Green, Blue, and Brown. None of these wires when provided signal (i.e. input from the stereo) do anything.

On the passenger side there is a area that the PO sliced into and there are two bundles of eight wires. I suspected that there were speaker wires (Maybe a there and return from a hi/lo amp?) but none of these function either.

I'm lost... can anyone give me any guidance as to what color wires or where I should be looking to pick up the speaker lines? I can re-run if necessary, but I have to find them first and I would like not to pull the harness apart tracing it down.

Thanks in advance.

You don't have the service manuals, at least on CD?

I'd do that first.

The early cars were two channel radios with a front rear fader **** near the hand brake. Sounds like maybe the fader **** was removed and leads spliced from the newer head unit. So look near the handbrake for more wires !

This helps a lot.

I don't have the manual cd's yet; anyone have a reliable rennlister to buy them from?

Anyone have a wire color guide or know hi the lines from the rear speakers run?

They used to be available for download here: www.cannell.co.uk/Manuals.htm, but I cannot seem to find the 928 manual there today. P.M. me an email address and I will email you the '79 wiring diagram which should be similar. It is 1.5MB which should not be a big deal.

Get a 1.5v dry battery cell, and the wires you think may be speakers. Speaker wires are generally colour pairs, with a black trace on the negative. Put the black trace wire on the neg end of the cell, and wipe the other wire on the pos end - you should get a crackle or static like noise if there is a working speaker on the other end. Resistance will typically be 4-8 ohms. Car radio wiring has had std colours for many years now, but not sure how far back it goes - green, grey, brown ,blue. Some have a single black ground for all the speakers, with multiple connectors.
