Wiring a clients AFS-5600 using the supplied Stein-Air harnesses that came with the package. According to the manual it says to wire DB37 pins 22 & 23 for the CHT's on the Rotax engine. The Stein-Air harness is already bundled into the panel wiring, only to find there are no sockets or wiring installed in the back shell in those locations. Are terminals 22/23 the correct current wiring, or should something else be used? If those are correct, where do I get the sockets to install them?
