Ok i got headers there custom no name on it i guess there like ebay or something lol but my o2 sensor was by the exhaust m,anifold now its all the way at the end of the header where it connects to the exhaust piping itself (by the firewall) well i cut the old sensor off i noticed that there is a wire inside of a wire what should I do with them how should i run them? At the sensor its only one wire its a 88 STD hatch d16z6 swap. Thx for your help.

 

Anyone

 

when I replaced the O2 sensor on mine i just used a classic crimper like you would connect any wire and it has no problems
