![]() I did include the circuit from D75 to Pin 121/88 of the ECU in my applicaton with the use of Fuse 37. ![]() Apparently there is a need for it to be fused. I suppose the function of Pin 121/88 can be determined by removing Fuse 37 and see what happens. In the start mode, that circuit is dead at both the Load Reduction Relay and Pin 121/88 at the ECU. That circuit is only hot when the Ignition is ON. One goes directly to the Load Reduction Relay and the other goes to Fuse 37, then to connector 14a/10 and on to pin 121/88 of the ECU. In summary, current goes from D75 in the ignition switch, to Splice A80. Splice A80 is where it branches off to the Load Reduction Relay. On the way, it goes through Fuse 37 and Splice A80. However, it also goes on to D75 in the ignition switch. Clarification (not intended to highjack the Thread, but I have received a few PMs)ฤก4a/10 does go to the Load Reduction Relay.
