Installed a new dakota digital cht gauge.
I have this gauge but have not installed it yet. I have the wire run from the #3 spark plug up thru the tunnel into the center console area. How was it wiring it up? I was having a hard time figuring out which wire went to what for the light etc. I have to go back and do a search of what is what in the console. I already have the oil temp gauge , volt gauge and a AF meter wired up, so I assume I will have to do some splicing again and hack into the harness to wire it up. any quick hints ?
How accurate do you think the read out is?
IIRC, you just need a 12v & ground for the light in the gage. It is dead to the nuts accurate. Dakota's engineers are more than happy to assist with any questions or problems you encounter. Do they still offer only a 12 ft lead for the thermocouple?

I think they have a couple of different lengths for the thermocouple. Make sure you get/have the one that's the right size for our spark plugs. Wiring is pretty simple: 12v, ground, plus (if you want it), 12v connected to headlights for dimming.
I've been running a DD gauge for a few years now. I really like it, but I've noticed something interesting and would be curious if you have a similar experience. When I turn the heat on in the car, the CHT temp readings REALLY go up. I'm talking about the difference between say 310 degrees and reading 350 (or higher going up a hill). It seems to be worse if I'm blasting heat to the floor instead of defrost, and my gauge is under the dash.
I know little (very little) about thermocouples work, but I know it has to do with temperature differences. So I've pondered whether the increased temp readings I'm seeing are REAL or due to the thermocouple. Yesterday, for example, I had the top off driving home but ran the heat as it was a little cool outside. I didn't seem to notice particularly higher readings.
Interesting, I will look for that when I get the gauge wired. I did order the longer wire I think it was 16ft so way more than I needed and I had the correct size for our plugs, I put all that in when getting new tin back on motor back in July, but just didn't have time to wire the Gauge in the tunnel but the yellow wire is run all the way up in there and ready for me to slice and dice into my console harness to add the 12v wire for the light. I have not done this due to the fact that it will be an all day ordeal to make a new face plate to fit 4 rather than 3 gauges.
I was thinking about having the guy that does the carbon fiber ones make one for me.
once I have the face plate made it should get done on a Saturday. I just didn't want to tear into it before the Concours show in HHI this weekend.
I will watch the heat and see if the temp gauge is effected by the cabin heat etc. you would think this should not effect that gauge reading at all, but as you said I am not an expert in this are either.
