Ok i got the motor installed most of my check engine lights are gone. I get one every once in a while. Dont know what it is. But for some reason i had a weird idle. Well i got that solved somewhere i pulled a wire and now im not getting speedo or temp. I know that theres one wire on the side of the block that came loose. Im guessing thats the thermostat since its only 1 wire. where would the speedo wire be?

 

Speedometer is in the tranny. Follow it from your firewall right down to the top of the tranny.
