has anybody ADDED this option on AFTER they purchased the car. in other words...you had the original boost gauge then purchased the RPD and put it on yourself. is it hard to do? is it as easy as removing the old gauge (and panel) then connecting the new RPD? is the wiring already there behind the panel or do you have to hardwire it??


thanks TC'ers

 

I heard it's kinda hard and really expensive. You need a new wiring harness, plus the gauge.

 

what if a SC'er helped

I saw that somebody said they tried but it did not work.
I also saw that Scythe Snake (sp) said he added it after...leme check

 

yes it is possible. you need a new wiring harness and RPD

 

thank you!! we are ALL 'balters here man!!!

tough to do?? i put in a cruise control in my rubicon jeep...came with the harness, all i had to do was plug in all the connections...easy...i hope this is the same way...

 

The dash hawks look almost identical and way cheaper. But its all what you really want!

here is the thread. look at that harness. lol

 

post 6 y0!!!!!!!!

 

i fail. lol

 

now you win ^^^^^

 

oh man!!!...i don't think i want to pull my dash apart and screw something up...these cars seem sooooooo sensitive. i probably would set off a million codes of something....idk, have to think about this one. how much is it?

 

Harness was 371, new molding for the RPD screen is 600, and the RPD screen is 490+. I got MASSIVE discounts cause my dad used to work for gm. And it costs 1500 + labor.

 

waste of money!!! dont do it! It looks awesome but unnecessary. plus it doesnt show you vacuum.

 

thanks guys for all the help! thats why i love this site!!

 

Scythe, you did manage to get it to work?

 

get aftermarket... they are sweet looking.

ONLY reason I got the RPD on my 09 was -1- it was only a 250$ option 2- Came installed from factory.

I seen some sweet aftermarket gauges...

 

I might be able to get one for free if everything goes right. That's why I was asking. If it CAN work, I would save me $250 and I would still look stock and wouldn't have to spend money on aftermarket guages.

 

i have dual aeroforce inceptor gagues in a triple pod with the stock boost gauge in the bottom pod. real nice!! that is every thing you need! and then some!

 

But I can't come across one of those for free . How much did that cost ya?

 

I done a lot of research and found a way to add the RPD (option UAF) display to my car WITHOUT having to replace my instrument panel wiring harness. I wrote up a "How To" on how to do it but ADMINS/MODS will not post it up. I posted it almost 2 weeks ago on how to install it, what numbers I used, and how/what wires need to be attached to. Since I didn't really know what I was doing when I installed it, it took me about 45 minutes to do. But since I have all the information now it shouldn't take more than 20-30 minutes from start to finish.

NO programming is needed. It was just remove old a-pillar trim, splice a couple wires up there, install new a-pillar trim that also includes display, run 5 wires down to the DLC (data link connector you connect scan tools to at bottom of dash), tap into the high speed GMLAN wires, splice into the battery positive wire also located on the DLC, turn key on.

ALL done.

 

Very cool. So basically you're running an RPD like a typical Aeroforce/Dashhawk off the OBDII? It makes sense, it just seemed like you would need the elaborate wiring harness to do it at first.

I guess that also means that the RPD screen has the reader software in it to be able to read the bus on its own.

It also means that you may be able to plug it into another GM car with GMLAN and have it work. (RPD Camaro anybody?.. .. obviously boost wouldn't work) On that note, does anybody know if the SS/SC could benefit from this then? Does it have the right data bus in it?

 

That's correct. All I purchased was the trim which included the display and the connector that plugs into the display itself. The 2 wires that I used off the original 4 pin connector from the analog boost guage was just a ground wire, which is also located on the DLC, and the IGN Positive. All the rest that I spliced/connected to is located on the DLC.

The connector that goes to the back of the display is an 8 wire connector that has about 10 inches of wire on it. It's almost long enough to reach the DLC. I removed the door weatherstripping to hide the wires inbetween it and the dash. Then I just connected the wires from behind the DLC.

It might be possible for it to work on other types of cars since there was no programming involved.

I like it. It keeps that factory look. )

 

Do you know if this will work on an "08? I know the '09 uses different software.
