R100/7 - 1977 Mfg Year - Question on turn signal relay replacement options

Problem: Both turn signals are flashing on and can not turn off at switch with ignition key on.

Diagnosis so far: I have a strong suspicion that the turn signal relay, in the head light housing, PN 61-31-1-358-198 has to be replaced.  Does anyone know of an over the counter replacement, 3 prong.  Through one of several aftermarket options pricing is around $58.00. With some rewiring, I can purchase a Trisdin Stant 3 terminal for $5.50 and make it work.  Just wondering if there is a plug and play NAPA or equivilent available.


Thank you,

R100/7 Owner

If both are flashing with the ignition on and turn blinker switch off, the problem is not the relay. With the switch off there should not be a connection from relay to indicators according to the wiring diagram.
