    I am modifying my 69 Corvette to have Head Lights and Fans running off of relays.

    I purchased 4 BEULER BU-5084M relays that has a Negative Spike Suppression protection.

    My question is: Does polarity matter?

    Should pin 85 be grounded and pin 86 +12v ??

    I tried looking for the BEULER website could not find one.

    Thanks in advance for your help.
