Wiring a Car Stereo into a car without an adapter plug
Discussion
We are doing a banger rally across Europe in September. The rules are that you buy a car for less than £333 or that is over 20 years old. We have opted for the 20 years plus option and purchased a Porsche 944.
The 944 had a Sony CD player but it isn't great. I assumed it would have some sort of plug and as a modernish system was already installed I would just need to plug the ISO block into an adapter lead. I took the stereo out today and it is a multitude of wires into some fairly knackered connectors (which is probably why the sound is so poor). The previous owner has hacked the ISO plug off the back of the stereo and connected the wires from the stereo into a block connector then from the connector into the original Porsche cable through the knackered connectors.
So my question is this - what is the best way to fit the new stereo? I don't really want to hack the ISO plug off as the last guy did as I will probably sell the Porsche post rally and may take this stereo out. So I am thinking that if I buy an adapter cable with an ISO block on one end and cut off the plug at the other, cut the old connectors out of the Porsche, and crimp the adapter cable to the wiring in the car then effectively I will wire in an ISO socket for easy swapping of the stereo.
I assume this will work??!? Or is there a better way please?

I'd solder not crimp & use heat shrink to insulate them. But that's personal preference as I've had wires break due to the weight of connectors hanging on them. I know plenty of people why say aircraft use crimps not solder so crimps are better.I assume this will work??!? Or is there a better way please?

This is what you need, gives you some clean connections to join up to the existing wiring & gives you the standard ISO plugs. Used one of these on my old mans Evo a few years ago and it worked a charm.

1985 was a changeover year. They started building the 1986 model year car in September 1985 and it is virtually a whole new car. The wiring loom is completely different.
I have wiring diagrams for both somewhere, I think. It should help you make sense of the wires/colours, at least.
That is fantastic GC8, thank you! It is the revised (Oval dash) model. If you have a diagram that would help, otherwise I was going to draw the existing connections, cross ref to the new one and connect that way. I have wiring diagrams for both somewhere, I think.

Perfect Lee, thanks. Saves me getting a lead with a connector on one end and chopping it off. This is what you need, gives you some clean connections to join up to the existing wiring & gives you the standard ISO plugs. Used one of these on my old mans Evo a few years ago and it worked a charm.

Buy a new DME relay! If your car runs well now then keep it in the glove box. Itll cost about £25 from your local OPC or EuroCarParts. Never deal with Porscheshop unless you have exhausted every other possibility.
Id strongly suggest joining the PCGB 944 forum and the TIPOC 924-944-968 forum.
