Tyco bought out Bosch but it’s the same company making relays the same way. I ordered two 12 VDC Tyco 5-Pin Relays, SPDT 20/30A (Formerly Bosch) from Parts-express.com for $2.75 each. Part # 330-070. Napa’s closest mach cost $18.00 a piece. Part # 330-075 for a 12 VDC 5-Pin Relay Socket. $1.75 each.
