hey guys i have a 90 accord with the f22b1 jdm motor swap and im trying to install a 5 inch tach and shift light but its not going as smooth as i hoped. lol. me and a friend hook up everything the way we were told to but its not working. the shift light works and the tach needle will move alittle when playing with the power wire to the battery but as far as revs it does nothing. i know this is very open and it could be anything but any info would help. thx
