I drive a Demon (and not the other way around)
Thanks for your kind words. I am in the process of laying carpet. I got some foam insulation that I put in the floor boards after the JB Weld had cured a few days. Now that the insulation is stuck down, the carpet is going in. The rear set carpet in in place. I am having difficulty finding the strength I need to shift the front seat carpeting around to where I want it. The insulation in the front of the interior makes it not fit quite the way the carpet manufacturer intended.
Right on about the wiring. I followed the factory's practice of running power along the chase on the driver's side. All of the audio leads are utilizing the chase on the passenger's side. I have a 1000 Watt Amplifier that is going in the trunk. I am prepared to do without tunes when I need to run the "Rear Air". Hopefully, I can ground the blower motor well enough that there will be no inductive noise in the audio.
I am looking at the underdash wiring. It has been hacked up, mostly for a complex aftermarket cruise control that had been in the car. A running change to the interior harness was made in October of 72. The earlier cars use the same harness that the 71 models have. Anyone happen to know if the later cars use the same harness as the 73s or later year models? This particular car was built in February of 1972. I am not sure, but I think the change in the harness was made to accommodate the EGR service light. I am not crazy about the outlay for a new dash harness, but even less so about repairs after a fire.
The radio, or more correctly receiver head unit, that I will install, is a Clarion DB285USB. I have an Owners Guide, but no installation manual. The guide is great for explaining all of the features of the radio, but lacks instructions on how to wire it up so that it works as explained. All of the input to the unit is through a block with wires running out of it. I have determinded what some of the wires are for, but not all.
The photo is of the block that attaches to the back of the Clarion head unit. The eight wires that are on the left are (what I think) are the speaker output leads. One of each pair has a stripe on it. I do not know which wire of the pair is + and which is - , nor do I know which pair goes to a particular speaker. The blue pair has female electrical connectors crimped on, They may be leads for a center channel, which would cause them to be replaced by the gray pair as one of the left/right-fore/aft pairs. I don't think it matters too much which lead gets connected to which pin on the speaker, but I will need to be consistent, i.e. Connect the striped wire of a pair to the red terminal on a pair of speakers. I can trial and error which pair goes to what speaker.
The wires on the right are more troublesome. Here is what I know. The two wires with in-line fuses are electrical leads. One has a 3 amp fuse, the other one has a 10 amp fuse. The 3 amp line needs to go to an un-switched power source because it controls volatile memory of the radio, in particular the station presets and the date/time function. The lead with the 10 amp fuse is the main power for the radio which means it needs to be connected through the ignition switch. The black wire with the claw connector crimped to it is the ground for the radio. Here is what I think. There is another pair of gray wires that maybe for one of the speakers, a center channel possibly. This leaves three wires that I do not have a clue what they do. They are not matched or distinguished with a fuse holder. They are a long red wire, a long yellow wire, and a short brown wire with a female electrical connector crimped to it. One of these will operate remote accessories such as a powered radio antenna or an amplifier. You now know as much as I do, or suspect that I know.
If a FABO member has an installation manual for a Clarion DB285 radio and would be willing to post an explanation of what each of the leads is for, please do so or PM me with your findings. If a FABO member has a DB285 radio installed and is able to determine what each of the wires works, same thing. Post an explanation or PM me. In the event a posting or PM is made, please let me know if you have the manual or are looking at a properly functioning system. In advance, thanks for any assistance you are able to provide.
