Hi JL, to be honest its been that long since I installed it I am not sure what make of solenoids I used, but i think it was a 4 door universal kit, I installed for central locking and the reaming 2 I used for the boot and fuel flap. I had to make an angled aluminium mounting plate to get the pull direction angle correct and then just used wire between the solenoid and fuel lid catch, then i wired it back to a spare connection on my Toad Ai606 alarm system which is well known, cheap and great for addons (I've fitted a close proximity senor to warn people away) and wiring with universal kit so now my single fob locks/unlocks pops the boot and pops the fuel.. I thought I had a photo of the set up but I cannot seem to find one, if you would like one i will unbury the MX so i can open the boot, but it was nothing special, a man of your skills would do a far better job.
Just found what i ordered on my amazon account - here is a link but currently unavailable but its nothing fancy, I didn't want something too heavy duty, i made that mistake before when installing on an old car i used the huge magnet type and every time it opened it went with a right bang!!!

I have done a few different things like shaving all the mechanical push switches and installed magnetic reed switches behind flush panels, things like that because I'm odd lol!!
ill see if i can start a build thread tomorrow, as mentioned before im not a great fan of sharing things, but the guys (and gals) on this forum seem a lot nicer and helpful compared to the keyboard warriors from old forums who have now jumped on to facebook (which I'm on but don't post on)
