You can do that if you wish..
I posted that the coil side of the relay was termninals 85 and 86. An ohm meter reading here will verify relay coil...or, simply pull the relay and put 12v to those terminals and see if the relay pulls IN...if it does , the relay is not your problem..if it does not, it is...
Here are the k17 relay terminals and the harness socket #s they fit into
relay terminals 85 [pin 5] and 86 [ pin 4] are the coil.
relay terminals 87 [ pin 1] and 30 [pin 3] are the contacts
When 12v is applied to 85 and 86, the relay closes contacts 87 and 30, allowing 12v to go to Clutch and SOV of AIR system. [ using fuse 7 as voltage feed]...so , if you jumpered 1 and 3 , the pump clutch should pull in if clutch circuit is OK. [ this would be the same as when you manually operated the relay contactor set]
