A while back I bought some Lamco gauges (boost, volts and air temp).
Getting the boost and voltage working was easy as, however the temp sensor was a different story. Tried a few sensors for things like Arduinos - didn't work. Tried an oil temp sensor - didn't work. Tried a coolant sensor - didn't work (these were all recommendations I found online). I did find a post the recommended splicing into your MAF to get a reading, I was a bit reluctant to do so.
So I found this on Ebay which was cheap enough to not worry about if it worked or not. Fast forward 3 weeks, it arrived. Hooked it up, and voila! it works
To get the right adapter all I needed was a donor ford and some side cutters - off to pick a part! found me a plug (most fords have an IAT sensor in the airbox - you could probably also grab the sensor from there)
Next step is to figure out where to put it....
