it is a speed density system, and they're a royal pain in the ass to get dialed in. jones has been trying to get his right since i installed his 6 years ago.
anyway, what i did was cut a hole in the driver side of the rear engine compartment cutout and ran the harness in there (can see in corner of 5th pic). it came with the black plate to cover the hole. then i stood his computer straight up behind his under dash console (6th pic). we never did mount the plug for the programming box, but he later velcro'd the readout box to the console.
