Good point, thanks for the help. I checked the harness and all the pins and wires are in good shape. I ohmed all the individual wires through the connectors, all great. I plugged the harness in without the EVO module and, no start with the key. I already know it won't start with the key (or remote) with the EVO module plugged in. I'm pretty sure the harness is OK, but should it start with the key if the harness is plugged in without the module? It seems like it should because all of the wires go directly from the male to the female plugs, with branches off for the module connections. So it seems like the car wouldn't even see the harness if the EVO module was not plugged in.
