alright heres the deal...i bought this car, its an 87 tII, from someone for 500 bucks and theres some stuff unplugged and unconnected that i have no clue goes to it....so...were gonna play the picture game

the little tube that looks like a mushroom....where does that go and what is it?...haha

Ok....the little water pump neck had some kind of sensor in its neck....in this picture

I went and got another one off an NA s4 and it didnt have the sensor..it has a little place to put on but no threads and the hole doesnt go all the way through....whats the sensor for?.....here

This wire connected to the sensor on the first thing


anyway....start flamin and namin

 

1. it's for AAS...you don't need it.
2. Jumper plugin. Don't worry about it...
3. Diagnostic plugin
4. Coolant level sensor
5. goes to another tube that routes to your front bumper...you don't really need it IMO...
6. Electric Fan for AC condensor (goes for the last few pics you posted)

 

ok

pic 1, idk, not sure that it really connects to anything

pic 2, nothing connects to that, you can jumper it to turn on the fuel pump if you needed

pic 3, some kind of test connectors, dont worry about them

pic 4, thats your coolant level sensor

pic 5, thats removed on mine (blocked off all emmissions and everything) pretty sure its not important

pic 6, looks like a coolant temp sensor

 

6 looks like someone drilled and tapped that for an aftermarket temp sensor. Bad place for it too since it's on the wrong side of the thermostat.

 

yeah mazda did do a few stupid things in the 80's

plug that one back in to your old neck or find another turbo neck if you cant use that one for some reason, like its cracked or whatever.

the water level sensor wire that plugs into the one in the radiator is probably hanging out in that big mess of wires by the passenger side headlight..

 

5 is for the air pump muffler, any air not being fed to the cats is dumped to a muffler below the RF headlight

6 is a coolant temp switch that works in conjunction with the A/C and engine temps

 

my question is do i need that temp sensor? or can i use the s4 na neck?

 

bump

 

you dont need it. its just for the ac electric fan but its always a good idea to keep the motor as cool as you can.

 

the airconditioning pump is gettin ripped out before long.....so basically i dont need it unless im runnin a/c?

 

bump

 

Pic #3. The larger connector goes to the ECU this is where you tap in to get you DTC's out. The smaller connecter is for setting you idle, jump this connector and then set the idle remember to take the jumper wire out when the idle is set

 

Some FCs came with an electronically adjustable suspension, with a set of buttons near the emergency brake handle.

That plug is for the small electric motors that should be mounted on top of your struts, both front and rear. If you still have the stock suspension with the adjustable struts, there should be a cable coming out of the rubber cover on each strut tower.

I'm assuming this was removed long ago.

 

the only one that you need is the single male bullet connector on the radiator. that is the coolant level sensor, and it is important to have. the rest are unnecessary, especially if you dont have ac.

 

i belive only the s5 gxl came with the aas suspension

 

no i have a 88gxl with aas (thats the one with the sport and normal switch right?)

 

I had an '87 that had it... I knew nothing about RX7's then so I dont really remember the trim... I still know little about them but I want to say it was a GXU if that exists... It was a GX(something)... Heck... I dont what trim mine is now... lol...

 

s4 and s5 GXL had aas suspension

 

no....S4's came with it too...and all FCs had the same harness plugs for em....
