I was thinking, since I'm getting Double Z to do my harness for me and it'll be plug and play, couldn't I just snip the wire off of my stock cluster, and solder it onto my tach signal wire?
Nope, there's no tach signal wire going into the cluster. It's all part of the data stream. No data stream, no tach, no coolant temp. The microprocessor decodes the data stream and moves needles accordingly. I feel this has been discussed, the answer is not gonna change.
Alright I am bringing this one from the dead just so I dont post in the how to section. I have been reading this for the last couple days and having trouble figuring out something. I have recently bought a 99 GASE w/ the 3400. I am going to build the motor b4 I put in my 97 cavy. I am trying to figure out what wires do I need to keep on the cavy pcm to run the gauges? Thanks guys.
It's way cheaper than buying any aftermarket gauges. He already has the stock ECM and wiring, so no money spent on that.
As far as what wires to keep, you need to run the sensor wires for anything that will affect your gauges (coolant temp, oil pressure, speedo, etc.). The tricky one is if you have a tach, since that's part of the serial data stream. I don't think the 99 GA uses the 8192 data rate and protocol, so if you have a tach, it will not work.
Fuel level sender wire has nothing to do with the ECM in 99, so you won't even have to worry about that.
I haven't found the answer yet, but I have to admit I haven't really been working hard on it at this point, but it's possible that the data stream description portion of the ECM flash can be rewritten. I have a whole bunch of description files for various vehicles and engine configurations, and the tach signal is a different location in the stream for the GA than the J-body. I have not found a 3x00 ECM that has it in the same location for the 8192 baud stream.
Now, I have had an idea that I would love to try out, but not on my current project, because I have a custom cluster, but the 00+ Buick Regal's have a gauge cluster that is very similar in size and shape to the J-body cluster. I'd love to try swapping the wiring harness, ECM, BCM, and gauge cluster from one of those for a swap. I think they're pretty sweet looking clusters, too, so it would definitely be a mod that would be unique. I'm sure it would require some glassing to the dash, but it could still be made to look factory if done right.
i gues i could do away with piggybacking the j's ecm and save some room and just buy separete gauges, and back on page 3 do u hav more pics of the digital gauges? and its easier or not to put separate gauges in?
Something like what Quik has is not going to be cheap... probably in the neighborhood of $1k
You could source individual gauges and install 'em for less than that. The individual ones are not difficult to install. Just need switched power, a good ground, illumination wire and the signal source. 3 of those are already in the IC harness, the signal source, depending on year, can be tapped from the IC harness or a separate sender....
make your own bezel, core out the back of the stock cluster and all set.
I know the two dakota's that I have in my a pillar cost me around 200 bucks, thats just fuel and oil and oil sender. Couldnt imagine what his setup ran. I thought I saw a speedo too, cachinnnngg $$$
Maybe these will work for you.
Here is a company that sells fairly nice looking gauges at a decent price, I have several in my s10, not any problems but I havent driven it much either. http://www.glowshiftdirect.com/
they sell the same thing on ebay but its cheaper through the web site.
