I have an 87 N/A RX7 and i want to take Everything that i dont need off the car i was wondering if there was anyone who had pics of a project like this.. its mostly the electrical i dont know what to do with... which things are ok to take out and wich are not... the wiring is really bad already so i want to make evrything basic and just hardwire the essentuials like heater!

 

the FSM is what you need.

are you tearing it down to the frame and swapping it into another car or what?

 

no sorry just want to take everything out that isnt necessary weight reduction / just dont want it in there and want it basic as can be... i need help with what wires can be removed i guess i could just start ripping **** out but if there is a right way to do it i want to know i havnt ever really dun this before

 

By slimming the harness you are taking on a bigger project then you think. It is very involved for someone to tell you how to do it over a forum as there is a lot of wiring in an FC (for a car of the era, anyway). Your best bet is to get a copy of the wiring diagrams from the Haynes/FSM (see FAQ) and get some familiarity with the wiring in the car. Then you can decide what can be removed.

I'm almost willing to bet that when you see what you are up against, you'll rethink saving weight in this particular area.

 

Stripping the wiring harness is somethign that interests me. 20 year old wire loom is nasty and brittle and the harness is full of useless crap. I would love to tear down, simplify and re loom the harness.

 

^^ i wish you all the luck. that is one big job and i suggest you get the haynes manual and alot of time and patience.

 

My electrician friend did it in his 87 sport. I don't remember his mods but he kept up with stock TIIs years ago. I give him **** everytime I see him because he the car and threw away all his notes from when he rewired the car.

 

I'd love to do that in my "new" RX-7, too. Maybe in '09, cause theres no way I'd do it during race season, which is unfortunately all summer long.. lol

If you do it, take all notes and keep them and post them on the internet for all to see so that it'll make it 100x easier on us..

oh yeah, and do it

im just gunna start ripping $#!+ out one at a time.. i have the repair manual it might help... ill try and get as many notes as a can if anyone can let me know of anything i DEFFINATLY should NOT remove please let me know now!!!

 

ummmmm, i don't think it's a good idea with the haynes manual. MAke sure you research this further before doing anything.

 

k.. i cant find anylinks... couldnt i just go through it step by step like... remove dome light..follow wieres and remover it all the way down to wherever it goes?? then do the same thing with like lets say heater... ect...

 

Guys who race in demolition derby turn the car on and then clip wires until the car stops. Then they reconnect that wire. It's a barbaric approach.

 

ya, forget about messing with the wiring harnesses at all, unless you have a standalone and some good notes or step-by-step instructions. or unless you have done it before.
just fahgit bout it!!
seriously, leave it alone.

peace

 

The Haynes manual will be a great help if you have the base knowledge to do this. It has fairly complete wiring diagrams and you can use them to eliminate circuits you don't need.

Quite a bit of wiring can be stripped from the car if it's going to be a full track car. However as far as I know, no step-by-step guides exist. You'll have to look at the diagrams for your year of car and go from there.

 

If you're trying to shoot for better racing times, you could probably just leave out the wiring as far as weight reduction...
The amount of weight a few wires yields for loss time can be gained up in skill of driver. Assuming you've done the proper weight reduction (seats, carpet, emissions, etc.) to start with the wiring. I'd say you're pretty much done at this point

 

This is about as bare bones as it can get.... Without running a carb that is.

Basically no heat, No A/C, Just guages, engine harness, and coils...

I have restrung and eliminated stuff on a 2nd gen project before. It took me about 8 hours straight to do it.. Not worth it... You can unplug and cap off the rest of the stuff... But messing with an already "crappy" harness is asking for trouble..

 

It's probably less work and you'll have a better end result to simply remove all the stock wiring and install a "universal harness" from painless performance. Find their web site here: http://painlessperformance.com

I've stripped the harness of my S4, it was alot of work, though the end result is OK it's kindof annoying to still have a FC fuse block seperate from my haltech fuse block... I could integrate it all into one but meh... the R1 gets all the attention now.

 

thats where im sittin right now... except have the heater still (its cold) but its direct wired with a switch all or nothin...umm anyone know how to manually switch from face to defrost?? can it be dun?
