I'm relocating the stereo from its position up high in the dash to down in the center console. I got a Metra adapter for my new Kenwood stereo (Excelon X-998) which will adapt the Kenwood plug to the Saab factory plug.
Here's the harness I made with the Kenwood plug at one end and the Metra (same as the SAAB female plug) at the other end. Basically you connect the B+, ground, lighting, dimmer, etc., wires on one to the equivalent wires on the other. It's nice because I like to solder wires together whenever I can, instead of just twisting them together and using wire nuts.
I also tapped out the B+, ground, and illumination wires at each end. I'll use these at the radio end for a map light and an outside air temp gauge in the future.
On the other end, which will be up behind the dash, I'll use those wires for the voltmeter and the gauge lights.
I'm putting a voltmeter and mechanical oil pressure and water temperature gauges in the DIN slot at the top of the dash formerly occupied by the radio.
On my other 900, my gauges are in the same location, and they point straight out. This time I decided to angle them toward the driver (also known as me). Autometer sells a set of mounting rings that will let you angle them on a horizontal or vertical (or both) angle.
You can see in the picture above, they'll stick out a bit, so I trimmed them at certain spots so they'll slot into the dash properly. We'll see that after they're all installed.
Other than three small wire nuts which were unavoidable, every connection on the stereo, gauges, and speakers are all soldered or have connector plugs for good reliability.
I was actually running the front speaker wiring when I took the shot above. You can see my helpful "hole for wiring" finder (aka Mag-Lite) pointing into the DIN slot. Shine a light in and you can see possible places to run a wire.
It will be large enough the run my gauge sending lines through! Whoo hoo.
Note the factory grounds - more proof this car was built by human persons. Say no to robots. Just say no.
The larger black hose at the top is for the water temp, and the white nylon hose is for the oil pressure.
This worked out well - no new holes had to be drilled.
I'll eventually tap into the water hose that runs from the engine block to the "in" on the heater. The oil pressure gauge will tap into the threaded hole where the oil sender currently lives.
I'll finish that up when the weather is better, but I needed to get the wiring all in place while I had the dash apart.
Here are the two old speakers - you don't need a sharp eye to see they were different! One was a Pioneer TS-A1090 and the other one was a JBL GT42TO.
I'll keep them for future experiments...bwahaha.
You can see that old wiring in the white box running along the sill.
There's a big 'glove' rubber grommet between the passenger side kick panel into the engine compartment. Cut a slit in it to run wiring into the engine room. Easier than the driver's side!
You can see the B+ cable, the speaker wiring, the interconnect cables and the power amp turn on wire.
I kept the B+ away from the others as a hum-reducing measure...it's the amp builder in me :-)
