I have a 68 cutlass with A/C removed- I got the A/C delete cover and want to hook up just the blower but cant seem to get it. The wiring was a little burnt up / dry rotted at the plugs so I have replaced the blower relay and thermal limiter and ditched the plugs. Is there another a/c relay I need to get vairalble speeds ? blower works when jump wired. Do I need the power line that has an inline fuse to the horn relay ? didnt ever seem to do anything. I guess I just need to know where the wires go to these components to make purple wire to blower work at different speeds. I have a feeling that Im missing a part from the a/c engine bay side I have seen mounted in a/c case. Would appreciate any help. Thanks
