Relay Question
I have all red relays from the PO in my '89 Targa. Is there a problem having all red relays or should I replace all but fuel pump relay?

Thanks

No problem..the red relays have a diode built into the coil to allow a path for current when the relay is switched. This prevents voltage spikes. The black relays do not have the diode.
