I have recently swapped out my tbi for edelbrock multi-port fuel
injection on my 454 1 ton chevy. I removed my factory ecm computer to
install edelbrocks computer. Well I have a th400 that wont shift
automatically because that little orange wire that comes off of the
tranny is just hangin there. I couldnt find a kickdown switch at all
on my throttle on the tbi or on the gas pedal in the cab. I know
theres a transmission relay on the firewall. According to mitchells
wiring diagrams the little orange wire goes to the transmission relay
then to the computer I no longer have. Is that correct and if so what
can I possble do to get transmission to shift. Any help would be
great because Im totally stumped.
Because the edelbrock kit that I put on there is for 86 and older
basicaly before computer controlled motors. I purchased that
edelbrock kit because its totally programmable to my likings on how I
want the motor to run per like towing or freeway you just add more
fuel or spark were you need it. They dont make a kit for 87 and newer
were you can program the motor, they only have a kit that works with
the factory computer for those years.
