Mike65 475 Report post Posted August 27, 2017 Over the past few days I have been installing misc items getting ready for the complete rewire of the car & I am to the point of installing the 2 relays for the dual cooling fans,& 1 relay for the EFI electric fuel pump. I am trying to decide if I should mount them under the hood or in the interior. I read one article on installing cooling fans & it said they should be mounted as close to the power source (battery) as possible. I was thinking of mounting the 2 relays & 2 circuit breakers for the dual cooling fans on the l/s front inner fender panel & mount the one for the electric fuel pump in the interior with the inertia switch. What do you think, or do you have a better placement for them. Quote Share this post Link to post Share on other sites
det0326 179 Report post Posted August 27, 2017 Hi Mike I replaced my alternator with a 3G alternator which allowed me to remove the old style regulator and gave me a little more room on the passenger side. I managed to get 6 relays there but it is real tight. I don't think I would do it again because it makes it harder to work on if needed . So my suggestion would be place them where they can be easy to get to for repair if needed. I had a bad connection and had to remove about everything to repair it. Then again I guess that's typical of these cars. Dave Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted August 27, 2017 Granted, I moved the battery to the trunk, but this is where my fan relays are located. The headlight relays will mount to the left of the installed relays. Quote Share this post Link to post Share on other sites

I cut a relay box out of a crown Vic and put in the mustang before I found this. Replacing It with this one in the near future. I ran lights,horn,fan off relays . set half of fuses to 12v ignition ,half to constant hot. Quote Share this post Link to post Share on other sites
