CLUTCH INTERLOCK RELAY. TEMPORARY BYPASS.

Nissan Truck

92 Nissan hb pickup 4 cyl 148,000 miles

I had a no start problem and isolated it to the clutch Interlock relay. I have no manual for my car so, cannot tell which wires to it go to what. I need to temporarily jumper the contacts that the relay would attach to so that I can get to the dealer for the part. I have no one whom can take me there during business hours.
I have the contacts jumpered like so,
one jumper from contact #3 to #5
One jumper from contact #1 to #2.
This starts the vehicle but, am hearing an almost "pre ignition' noise when starting it this way.
Is there a connection here I should undo? Thanks much!

At clutch interlock relay: The blk/yel is coming from the key-and the blk/pinky to the starter solenoid jump this straight across.

The light green goes to the clutch interlock, when clutch pedal is depress it provides the grounding thru the interlock relay this will tranfer power at the switch side of the relay straight to the starter.

Hope this helps

Thank you very much for your reply!
Could you tell me in terms of the number of the contact ponts on it/ my knowledge of such things is limited. I have them connected this way.....
