So i have a 1988 subaru that recently had a ea81 swap with a weber setup. Everything works fine except the temp gauge. I picked up another coolant temp sensor to see if that might work but its a 1 prong and the one in the manifold is 2 prong. Im not sure the year of the manifold but i think its 85. I have a 87 Factory Service Manual and the manofold in the car for SPFI and Carb are not the one that is on the car.
1. Am i missing another sensor somewhere. The 2 prong is right next to the T-Stat housing.
2. Could i use the 1 prong anyway with the 2 prong connector.
3. I thought the 2 prong was for the computer and there was a 1 prong somewhere that just did the gauge.
