Blazer overhead console install

[Ingandreal]

So i went to my local Pull a Part yesterday looking for a explorer overhead console, and couldnt find any as we all know theyre popular as well as the dissapearing sliding back glass for the Ext cab. So as i was walking out, i came across a 1998 Blazer with a full overhead console with 4 map lights, courtesy lighting, Temp, Compass, MPG AVG, Tank Range, avg speed, 3 door garage door buttons built in, CD compartment and Sunglass holder. I always thought it would be nice to have one of these in a ranger, so i grabbed it and got away for less than 5 $. The consol is in perfect condition and i cut off the wires between the Clips and the main wiring harness. I placed it up on my headliner and it looks like it will fit well. Tomarrow I plan to wire it all up and mount it. Im planning on writing up the entire install for the rest of the forum members. Though its a chevy part, it seems to fit well and t wiring is almost the same as the explorer wires and It has wires to go to the Data system in the computer. Im looking into finding a way to get this hooked up so i can get the AVG MPG and such to work. I will keep you all posted and heres some pics of a close match to what i have.





Was wondering if anyone knows if the 93 4.0 computer has a feed that outputs the data needed to fullfill the needs of the MPG/Speed part of my Driver Info Console?

Fuel flow probably comes from Pin 34 on the computer, it won't be drilled out on your computer so you will have to do so manually (at least, it does on the 2.3 computer). The speed will come from the same cable that the Explorer OHC wants hooked up.

That said, I would highly not expect it to work. I doubt that Ford and Chevy use the same style of signal for fuel flow, and probably not for speed either.

Either way, looks great!

Well i wire everything up and i have all the lights working, Easy part... I also have the display illuminating and showing direction, but the problem is it doesnt change when i turn. I hooked up the Vss to the CC Gray/blk wire like in the explorer to ranger mod. So after reading on a blazer forum, i found how to reset the compass and did so but now is just reading C for the direction. I dont know where to go from here so im going to stop at the local pull a part again and see if they have a 97 computer for the display because it runs off a simpler signal than the Data Class 2 signal for Vss. Im hoping this may work, if not i plan to see if i can get a display out of an explorer and maybe it will fit into identically into the encasing. I hvent gotten the temp sensor wired because i still hve to get that off the blazer at Pull a Part. If anyone has ne info on blazer consoles that would help me id appreciate it

Yeaa it does, id say theres 8-10 inches between the back window and the back of the console. Looks great tho. Doesnt match up perfect to the ceiling lines so when i wrap my headliner again, im gonna glue some foam underneath t fix the gapps... should look great.

Off topic but does anyone know if a 1988 rangr extend cab window would fit my 93 ext cab? they both bolt in and i cant finda used slider window in the 93+ bt i found a 1988 at the Pull a Part thats almost already removed

So went to the local PAP again today to look for the TEMP/COMPASS only display (other 1 i have has speed avg, est economy, MPG and such) and i grabbed the temp sensor off the Radiator mount on the blazer. So after work i pulleed down the display i had, cut the wires and re wired everything to the new display. I put it back into the Console and then mounted the Temp sensor and then Calibrated it. Works great!... Im guessing that the VSS is working because its taking readings constantly and showing the right direction and temperature so it doesnt appear to have a problem with the Ford VSS. Im guessing that if i took a Explorer Display and the Blazer display and put them side by side they would be the same. So in a few days Im going to re headline my truck and add some foam to bridge the slight gap in the front and then ill take pics and do write up on the whole thing, Wiring, Cutting, Mounting, Display calb and funct, and such. Hope youll enjoy it and maybe ill be seeing some rangers around with it!

Im doing this now I wasn't sure if the GM unit would work with the Ford VSS signal as the ford signal is 8000ppm and the gm signal is 4000ppm so the unit would think your driving twice as fast. I haven't mounted mine yet but i had it connected with jumper wires and the temperature was working but the compass was somewhat erratic. I think playing with the variance zone might fix that. The unit looks like it needs slight modifications to match the headliner

Mine was out of a 2003 blazer and has temp and compass, no mpg or additional stuff.
