I just did a t-5 swap on my car and now it wont start. The only thing i can think it is is that i got the wrong harness from the tranny to under the hood. I think its one out of a newer car since it doesnt have a place to plug the speedo into and has 02 sensor plugs on it. Would that cause the car not to start? im getting a new one but just wanted to try and run the car if i could until i get it.
