Blazer Overhead Display Upgrade

cr8390 -> Blazer Overhead Display Upgrade (5/23/2008 5:06:33 PM)
Hey i know there has been alot of talk about the overhead displays in the s10's and blazers about how to add them or upgrade them from the Temp/Compass to the mpg,range, and all those other things. Well i looked up on ebay how much the display would cost it ranged from 45-100 dollars. I went to a junkyard today to see if i could find one. I did. After looking around a while in blazers i had no luck so i looked in Astro vans and boom. I looked up and saw it, i cut it down and cut the harness with it. The trip computer has a 9 pin harness and the compass/temp has a 6 pin connector. The harness i pulled had 1 extra wire 2 pins arent used or dont need to be. I installed and matched the first pins with my orignal 6 pin connector and spliced them togethor and electric taped them. The last wire pin 9 goes to you Data link connector that mechanics use to scan your computer. Find this connector find the purple wire and splice the wire from your last pin on the harness to the purple wire on the Data Link connector. Done! To reset it go to MPG and hold the 2 buttons for 2 seconds and all the numbers should flash and reset. This is easy if your just for upgrading from a comp/temp to a full computer with range mps and all that. Pop off the front cover and push the back in and the unit should slide out then you can pop the other one in. By the way i ended up paying $5.00 for the harness and the full trip computer unit. Instead of paying alot online. My junk yard was a self serve one so getting a person to go out and pull it for you might be hard cause they get no gain from it. Any 1 has any questions leave one here. By the way my blazer is a 1999 LS. I dont know the year of the astro i pulled it from.

That is a real good idea. Thanks for the tip. I was wondering if it could be done after someone tellin gme it was an LT thing and my LT didn't have it. I will have to do this, and it gives me a reason to go to the pull it yourself junkyard, woohoo! The only question I have, and since I haven't done it yet is why I don't know how, is to get the overhead console down off the ceiling.

NVANZEE -> RE: Blazer Overhead Display Upgrade (5/23/2008 8:08:10 PM)
how can i do this if i dont have the temp/compass to begin with. Is the wiring harness already above the headliner or would i have to run all the wires.

cr8390 -> RE: Blazer Overhead Display Upgrade (5/23/2008 8:37:34 PM)
To nvanzee you would probably have to rewire all the stuff i heard it can be hard to do ill try to find a link for it. and davtak there is a screw in the front of the overhead console the very front, its a little hole lookup theres a screw. Then take the plastic light cover off and there are 2 more screws in there then it drops off.

NVANZEE -> RE: Blazer Overhead Display Upgrade (5/24/2008 4:25:35 PM)
ok thanks cr8390 this is something i would really like to do

99blaz -> RE: Blazer Overhead Display Upgrade (5/24/2008 5:54:36 PM)
Sweet! I didnt even think about doing that but I might just now. Thanks.

myol blue4x4 -> RE: Blazer Overhead Display Upgrade (5/24/2008 7:00:41 PM)
I have to say thats a really good idea. But I was wondering, did you switch over head consoles completely or did you just pop out the display from the astro and hook + pop it back into the blazer console?

99blaz -> RE: Blazer Overhead Display Upgrade (5/24/2008 7:19:17 PM)
I'm pretty sure you can just swap the displays instead of the whole console.

myol blue4x4 -> RE: Blazer Overhead Display Upgrade (5/24/2008 7:23:27 PM)
Ok, yeah I looked on ebay real quick and saw that they are close to or if not the exact same thing so I think I might take a trip to the local junkyard and take on another project haha.

cr8390 -> RE: Blazer Overhead Display Upgrade (5/27/2008 7:06:31 AM)
I went to the junkyard pulled the overhead console out of the astro and popped the computer out of it and cut the harness down. Because the harness's are differnet on my truck with the comp/temp it was a 6 pin and with the full computer its a 9 pin. So u wanna get that harness. The first 6 pins on the 9 pin harness are the same as the 6 pin harness in your truck (the wire colors were different but that dosent matter). By the time u get done putting them togethor you should have 1 wire left hanging it should be the last pin, pin 9 u just take a wire from that to the purple wire on your data link connector. I didnt wanna replace the whole overhead console because it wasnt needed and expensive.

danmiranda -> RE: Blazer Overhead Display Upgrade (6/1/2008 9:21:53 PM)
Thanks for the idea, thats the one thing I admired in my Dad's venture. (If your doing this, thats another place to check Ventures, and Uplanders if you find one) I'm definately doing this, thanks man.

jukdd -> RE: Blazer Overhead Display Upgrade (6/2/2008 3:27:34 PM)
can you do this to a 95 blazer with compass and temparature. just making sure, this is a great idea for mine.

tkf5651 -> RE: Blazer Overhead Display Upgrade (6/2/2008 8:03:49 PM)
any chance of some pics?

cr8390 -> RE: Blazer Overhead Display Upgrade (6/4/2008 5:10:13 PM)
Yea i can post some of what it looks like give me a couple days. And it was no problem everyone i wanted to do it and couldnt find much info so i figured i would throw it up.

jukdd -> RE: Blazer Overhead Display Upgrade (6/4/2008 6:10:12 PM)
thanks!

Davis83 -> RE: Blazer Overhead Display Upgrade (6/16/2008 4:35:44 PM)
Pics or wiring schematice would be nice... I have 1996 Blazer with 6 pin connector (compass/temp only). I have a display from a 2001 that has 8 wires? When you say the 1st 6 pins are the same (irregardless of wire color) - which side are you starting from? So far, I cannot get anything to work - schematics would be nice if anyone has access to some.

95_4door -> RE: Blazer Overhead Display Upgrade (6/16/2008 7:17:10 PM)
Would I be able to put this in mine or will it even work. I am not using any of the sensors from my original engine. I think it would be a pretty cool feature if it would work.

swartlkk -> RE: Blazer Overhead Display Upgrade (6/16/2008 8:13:16 PM)
Search function works wonders! LOL Overhead Console

neo71665 -> RE: Blazer Overhead Display Upgrade (6/16/2008 8:41:53 PM)
Any of ya''ll wanna get rid of the temp/compass only part? I have a first gen and I think it will be a direct fit in mine I''ll just have to wire it up and get a temp sensor.
