Hi, I have an 88 firebird that I just bought and somebody did a real good job of hacking the wiring. I was going to stay with the electronic speedo. I'm going carbeurated. I don't know how to wire it back up, I have the haynes manual with the wiring diagrams. It was originally an automatic trans with a v8. I know I have to buy an electronic speedo, for my t5. Is it just a 2 wire sensor. thanks
