97 DIC Only Fits 97's But can you ....

Not sure if this is a "General Tech Discussion" or "Audio, Security & Visual Electronic" so, I guess here first :-)

Every post I have read said only use 97 in 97. Seems that 97 has a low tire pressure light. Looking at all the instructions I don't see a difference in how to wire them, other than 97 has a wire for the low tire pressure light. If you don't care about the low tire pressure light.
I did find a wire diagram that had a pin (A4) labeled "Check Tire Pressure ('97 Only)" and pin (B10) "Fuel Level Input ('97 Only). Since most of the wires look like a signal (on/off) except for the DLC. Doe the DLC of a 97 vs 98 have different protocol/messages? Is the (A4) and (B10) connectors show stoppers? The 98 was a GT so I should not have the reverse Trac light issue.


It's not end of the world if the DIC will not work, I bought both HUD, Trim, and DIC for 40$ and as far as I understand the HUD should work on all models. If the DIC doesn't work then I can always peddle it. I ask some question in the "Audio, Security & visual Electronic" about what some part's are and if the HUD in 97/98 have a control like my 07 GXP that changes the position and brightness. If anyone see's this and knows the answer, would you mind posting it there for me. Thanks in advance.

I have another question, is there any write up that explains how to bench test both the HUD and DIC? I am assuming if you give it power, it should power up. Then toggle the lines to see different effects. My question is what is (On/Off). Is it ground or Plus? Is it protected with pull up/down resistors? Of course you will not have anything that depends on the DLC wire. But seems like everyone who got the DLC wrong the display showed 0.00.
 


I installed a 97 dic on my 2000, all I did was just cap the low tire pressure light. About 2 months of using it now and it with perfect give me a little too see if I can find a write-up on how to install them both
 
I don't know how to test them beforehand but if your dic doesn't light and you are sure it's wired correctly you can replace the bulbs with the ones from your analog dic, I actually had to do that
 
if I were to try and test them I would use a small battery and find the power line and a ground and connect a wire to them, this should light up everything similar to when your car first starts
