Thanks for the comments.
I'll try to answer best to what I know.
Fuel pump strainer/filter, drop the fuel tank to do that. I have dropped the tank way to many times that it's an easy job for me now. Just make sure tank is empty lol.
Rear hatch release uses a cheap eBay universal actuator that's wires up to an aftermarket remote locking kit. (All of my wiring stuff is from my 98 coupe from way back) It had central locking and I wired in an kit. It's got a boot unlock button that I wired up a ground relay trigger to open it. Very simple. No forum post used done all myself.
Climate control is a mix from EVO and FTO parts. I used that exactly same post from Auslander that was created in 2011 or 2013. (Can't remember) I used whatever info was on that post. It worked for me, granted I did that swap maybe 2020/21 I can't remember now. ( It was done on my white coupe)
Foglights are not oringinal from Mitsi. I got stooged by the guy I got them off. Granted payed $50. Made my own brackets for them. I spliced the factory plugs into the foggies. They used the factory plug/ wires, which clip into the factory loom. As my OG 98 coupe had all the wiring.
Powered windows and wiring for my mirrors are all Mitsubishi original wiring from my OG 98 coupe. BUT the mirrors I have now are factory Evo 4 and 6 heated and folding mirrors. I made my own looms for all of them. Using an FTO module and switch, all my own wiring. (Sadly my passenger mirror no longer folds, no idea why AND I even bought a new
brand new mirror... And it still didn't work

) folding mirrors and heated mirror wiring was done myself with a tiny bit of research using some lancer forum from the states
Alot of the info was taken from Auslancer. If not research from other places online, or trial and error. Sadly I haven't documente
d alot if it. Hope that helps

Also these mods have not been done hastily. Some have been close to 5/6 years in the making. Some 4 years. Some recently.
Sometimes I do a bunch of work before posting, other times I forget to post things. Other things have been easy to do. It's been quiet awhile
