Do you have any paper work or schematic for the aftermarket unit?

The provided install paper work is pretty minimal, guess they are assuming install will be done by a pro. I suppose I will just have to try it and see if dimming works and is at an acceptable level.

Nicely done !!!

DIC's left side is 92 or 93, right side is 91
I'm swapping in the 92+ simply because of the black controls look better with the CF refinish, all of the used trouble lights are in the same physical locations but..... I noticed there are some minor wiring changes going on here - effecting PKE (which didn't make it for 91), battery, and check engine. These lights come on by being grounded, as you can see on the 91 the PKE shares power with a bunch of other bulbs, then they separated it in 92 and moved it to pin 13??? So PKE uses pins 13 and 14 on the 1992+ and pins 18-19 (shared +) and 14 on the 1991 part. This bumps the pins for battery and check engine down one. So anyhow I think I may have to take the wiring thingy (can't remember what its called) off my 91 part and transfer it to the 92+ part to make the DIC work correctly.

Playing around with the DIC also got me thinking.... I only really need 6 or 7 of these lights (about half the screen)... I could possibly relocate the trouble lights somewhere else and open up the space the DIC screen occupies for a GPS or even a multifunction device like what Jeff is doing with the Nexus 7... hmmmm

Yes, I mentioned that earlier int he thread

Yes and let me know if the intensity is off too far. You're not that far away albeit a different state.

Can't the lens of the DIC be transferred from the "required year" to be used right along with the correct PCB to make it all compatible. The only assembly I have is the '92 - '93 and the lens was removed I'm guessing for maybe use also. It was in a "box lot" of a parts purchase. All of the push buttons and the PCB was intact so I hung on to it.

The bulbs are getting difficult to source also -

Not sure what you are asking..

The PCB can be swapped and allow the correct display.

Locobob wants to use black in place of the grey for his car..

I understood his reason why!

I would think there's a likelihood of the "filter" arrangement in the lens might actually be different. I don't know that all years are the same, a '93 would certainly be different just because of the 2 lamp display for the LTPWS vs. I believe only a single for the earlier.

LENS I would think has different "filter" arrangements. Don't have one of each to check but I'd think so. '90 thru '92 maybe but '93+ different I'd think.

-=Jeff=- · 03-11-2014

If I recall right, the filter arrangement stayed mostly the same, the only difference was the PCB layout. I had a 96 Filter with 90 PCB when I did my dash conversion in my 89 many years ago
