i looked at the front relay box, and after taking out the relays i didnt need, i was only left with the horn and TNS. so i have jsut removed them, and used the end of a paperclip to remove the spade connectors from the box for them. the rest i jsut cut and maskered to the loom. havent tried it yet, but cant see anything will go wrong (famous last words!!!)

ok cool, thanks for that.

always good to hear what others have done.

Hey marco, what did ypou do with the fuel pump relay in the front relay box?

marco · September 27, 2008, 10:30:57 PM

from looking at the service manual, it isnt the main relay, but infact just switches the voltage down at low load. so (and it is still work in progress) i am going to take the feed from the main pump relay (which is in the other relay box- i think it is called b2 from memory) and use that to activate a relay that controls a feed direct from the battery to the (aftermarket) fuel pump. it may seem a bit \'round the houses\' but i am guessing that there is a safety feature in the car that will cut power to the fuelpump in the event of a crash. if i were to drive the new fuel pump relay from the ignition, then i would bypass this, and i cant help thinking that continuing to pump fuel after a big crash would be a bad thing....

yes thats right it isnt the fuel pump relay, it just knocks the voltage back for better fuel consumption
Marco I would take the fuel pump realy trigger from teh white and red wire, then it wont keep the power to the pump all the time if you want to leave the ign on for another reason.

ha ha, thats exactly what i am doing whilst we speak. also relocated the main battery supply (have relocated) to the starter motor, this minimising thing is quite addictive.

ross, i am getting nowhere with richard at aquamist regarding the WI setup, i will give you a call in a few days, i think i am at the point where i just have to bite the bullet and see if it works, as no one seems to have the answer!

karl_tate · September 28, 2008, 09:30:29 PM

good stuff guys, i will be doing both :cheers

maybe some more write ups are needed :p :King

went into the garage yesterday, got the door open and even got to turning the radio on, took one look at and ended up closing the door

just dont have any motivation at the minute and i have a million and one plans.

marco · September 28, 2008, 10:14:30 PM

to motivate you, here is a pic of part of what i have been doing today, it to allow rapid filling of the WI system.- also finished my WI tank, and once i have cleaned up the wiring done by the cowboy alarm installer i will wire up the WI system (and the wideband if i have the time. have jsut double checked my WI tank- 10 litres, and total stealth install:yes

karl_tate · September 29, 2008, 06:34:26 PM

looks good dude, take it you made it all your self.

what are you using as a tank, the rear screen bottle?? i got a bottle with my kit but im in two minds weather to use it or not.

marco · September 29, 2008, 06:49:36 PM

ha ha, no, as i need a bit more water than that, and the filler wouldnt be in the right place (plus the washer bottle has its own filler cap) i will give you a clue.
did you know that some rx7s came with rear bins rather than seats, and that they are one piece plastic with a lid that could be simply glued on top? did you realise jsut how much water one of them could hold with the lid glued on, that it would be really low to help with C of G, that the aquamist pump can be fitted in the front of the bin and JUST fits so can be hidden from view and would still leave the other (drivers) bin free for storage/ battery relocation.

(yes i am rather proud of myself, jsut have to do one final test fitting to makesure the hose from the filler doesnt foul on the chassis and its good to go. oh an i am goingto fab up some baffles to help with the sloshing. it will be two seconds of a job!)

karl_tate · September 29, 2008, 06:53:53 PM

cool, the filler doesnt look like its in the bin though, more where the tool kit is in the boot?? nice work

marco · September 29, 2008, 07:17:39 PM

yeah thats the plan, quick gravitiy feed down, and bigish bore (hose pipe dia) with seperate vent pipe so it will fill quickly. i was going to put a filler on the top of the bin but it would have ben fiddly to get the water in (have bucket seats), so moved it to the tool kit, easy to get to! should get some funny looks filling the tank with water at the garage!
