I have a 1988 HF and i have a head on it. The o2 sensor spot was moved far back behind the engine and i extended the sensor wire. It ran kinda funky so im going to solder the connections once i get a chance. But, i was wondering if there is an extension harness i can buy to make changing the sensor easier for the future? Also, will it be ok spliced and soldered? I only ask because it has to extended pretty far and dont know if it will mess with the way it run due to the length.
