Meziere EWP install....some tips for Fbodys just got done installing my Mez pump by using the ls1howto.com site.
the guide was very good, but i do have some corrections and tips to add. i emailed the guys at the site, but have not heard back.
wiring:
they say to pull the front fuse block and locate the large pink wire in under the Ignition fuse. but then they mention that when you "test" the wiring that it should be hot for a few seconds then turn off. which is NOT correct. tapping into the IGN line means that wire is hot when the key is on.
i assume they just converted the directions over from a corvette guide...and the wiring is a little different.
so, while this wire works, it means that your pump will be running any time you have the Ignition on. which isn't a big deal unless you spend alot of time sitting there with the engine off, but the key on. could be an issue if you do alot of tuning.
simple fix for something like that is to just unplug the pump under the hood. my plug is easy to access.
i assume you could just tap into the fuel pump fuse, which would only be hot for a few seconds to prime the pump.
pump installation:
[quoted from ls1howto.com]
"The bottom drivers side bolt will require a 10mm wrench (socket wrench HIGHLY recommended here) to loosen, and it will not be able to be totally removed from the hole as a pulley is in the way...this is ok."
this is true...
however if you take a 15mm socket and remove the pulley bolt, it simply comes off with zero effort. nothing fancy. that allows ample room to remove the lower bolt. and also gives a bit more room to slide the new pump back in, as well as the associated bolt.
