Aftermarket ECU

[Joel Wolcott <wolcott_jl@yahoo.com>]

Here are my questions - I am in the process of
purchasing an ecu for my truck.  Looking at Haltech
and Autronic.  Can anyone give me some real world
experience with either?

I have the original harness for the engine that i am
swapping in. Should i use the wires from the original
harness and splice into the ecu connector or use a
flying lead that comes with the ecu and wire up the
sensor connectors?
