EFI/ECM Wiring ???
My E-Z Wiring harness has a fusible link that is to be installed at the starter post/bulkhead and crimped to the #10 fuse block feed so that all feeds are fused. The Edelbrock ProFlo XT EFI is made as an add-on system for carburated engines, and the wiring has one power lead that they say is to connect to the starter hot post for a constant feed, and a second switched 12v lead to control the system. The fuel pump is controlled by the ECM, which is normal for an EFI system.
I am hooking the main feed from the + bulkhead connector to a four post terminal block using the supplied fusible link, then taking feeds to 1) fuse block, 2) SPAL Fan, 3) VA Heater/AC, and 4) ECU from that TB. The SPAL fan has an in-line fuse, and the VA has a breaker. My concern is the ECU feed, and especially the fuel pump - if the fuel pump shorts out the fusible link is the only circuit protection and that takes out everything. I'm thinking of replacing the fusible link with a Maxi-Fuse, and using a "Smart Fuse" that lights up when blown just to minimize the troubleshooting in a future problem, but I'm still questioning not having the fuel pump fused. Has anyone run into this, and how do you handle it?? In-line fuse in the pump wiring (not ideal, IMO, but may be the only way)?Roger
Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
Sorry for your loss of friend Mike McGee, Shine. Great trans men are few and far between, it seems. Sadly, Mike Frade was only 66 and had been talking about retirement for ten years that I know...
