Huge thread detour, i haven't even searched this site if people have done this on trucks. A quote from a member on fordfestiva.com:
"I like the idea of converting to a heated o2 sensor. As I recall the heated o2s were introduced to keep the engine from going open loop at idle when exhaust temps drop below a critical level. Part of the problem was location of the o2 for engineers. The engine compartment was becoming too crowded. By adding heaters the o2 then could be moved further away from the combustion chamber into the cooler exhaust gasses, allowing more room to move. Since their primary function is to keep the o2 heated at idle, I wonder if we would enjoy any MPG improvement."
The one that people use to upgrade a ford festiva (mazda 121/323/protege)is
I'm not where i can compare lengths if the festiva one is long enough to link up to the b2200 connection. I think its about 18 inches. Seems right. You can always extend the mazda harness but do not cut the o2 sensor wiring only modify the connections to make the splices you need.
