My 1983 De Lorean DMC-12, VIN 16908

Stereo Upgrade

I’ve always thought my stereo sounded way to thin, and needed an upgrade. There was practically no bass in the system at all. The previous owner installed a pretty basic head unit and speakers:

While my side panels were off, I decided to replace the speakers:

These speakers got good reviews with the other Delorean owners, and fit the rear location, albeit with better hose clamps and some persuasion:

I also took the time to upgrade the front dash speakers. I’m glad I did since the speakers the previous owner installed were very low quality. I found some Pioneer speakers that fit the location perfectly:

After some searching, I decided to upgrade the head unit as well. The new one features Bluetooth hands-free calling and audio streaming, wired external microphone, voice recognition, Pandora, USB direct control for iPod/iPhone, Android Media access, a remote control, and more.

It’s been said the stock wiring might not handle a modern stereo’s electrical needs. I took the time to run a new 12 Gauge yellow wire from the positive post behind the rear wall. A fuse holder is spliced into the wiring. Sorry, I didn’t get any pictures of that.

My upgraded negative battery cable features a smaller wire that was currently being unused. I found a new use for it: dedicated ground for my stereo.

Upgrading the wiring meant I got to remove all the glass fuses behind the dash:

While my A pillar trim is removed, I ran the cable for the microphone up the A pillar:

The result: The new features of the head unit are great!

I still think the sound quality isn’t great. It needs more bass. I’m going to have to investigate a subwoofer.

New Pull Straps

My pull straps had seen better days. They didn’t even match – one is leather, the other is vinyl: DSC_0226

Vendors were out of stock for many months. I finally found someone that had them made, albeit the “early style” with the ring:
DSC_0173

I took the time to replace some rusty screws and speed nuts. I also needed new bolts to hold them to the door:

I cut them apart, and squeezed them into my “late style” trim:

New Power Outlets

My cigarette lighter was broken, and the power outlet’s green plastic was cracked. I found an excellent replacement on ebay for $5.29 shipped: http://www.ebay.com/itm/360678268535
attachment DSC_0209

I knew that even if it didn’t fit, for that price I would make it fit. But yes, it fits perfectly. It’s a little more modern looking, and it’s blue! I measured the lighter drawing under 7.5 amps, and the lamp under 0.8 amps. I don’t know what the stock lighter draws since mine is broke. The only drawbacks I found were the light requires a separate ground, and it’s a little dim. I didn’t check, but I think the bulb is incandescent. I cut my wiring harness and added another female disconnect connector for the lamp’s ground.
DSC_0215
The power outlet I bought through ebay comes in other colors, even green.

I also wanted to add some power outlets behind the dash for electronics:
10242
Fuse 17 is rated at 20 amps. My cell phone and dash cam combined draw less that 1 amp, and my ’83 also doesn’t have a clock on Fuse 17. Adding two more outlets wasn’t a problem. Since Fuse 17 is live all the time, I decided on another mod:


After some fast shipping with DMC-MW, I cut the wiring harness and put a switch in the middle of the circuit. So now all my power outlets are controlled by the switch. This allows me to stop and start my dash cam whenever I want without touching the cam or the power connector.

My A Pillar trim is off the car right now, so I’ll be running the power for the dash cam behind the trim, then above the headliner.

New Custom Mirror Switch

I liked the look of the new Mirror Switch available from DMC-Houston, however the price was a little high for an unneeded upgrade. I know it’s made from a mirror switch used in a Saturn, so decided to try and make my own. I went to a salvage yard, and found one. Next I made a plastic plate to hold the switch:
DSC_0331     DSC_0350

I found the wiring connector online at britishwiring.com. I also found wiring diagrams online to help me figure out all the connections.
DSC_0530

I didn’t like how the DMC-Houston switch looked upside-down:
DSC_0527
I could see the polarity of the mirror motors was opposite of what the switch was. Up was down, Right was left, and so on. The options I had were:

  1. Do what DMC-Houston did: flip the switch upside–down, and swap the right and left mirror wires
  2. Reverse the wiring in my cars wiring harness.

I choose option 2. I pried the wire connections out of the mirror connectors, and reversed them. If the cars next owner ever tries to install an original switch, they’re going to hate what I did!
DSC_0528
Original mirror switches have been going for a good price on ebay, so I decided to sell mine.
DSC_0510 auction

Since I bought my car in 2007, my passenger mirror hasn’t had up and down functionality. I was happy to find out during testing that it was a dirty/bad connection.

I actually finished the switch in mid-2013, however I wasn’t able to finally install it until now due to my door panels being removed. Here it is, finally installed:

From the pictures, it looks like the interior is still kind of dusty. Time for a complete detailing.
