so as the title says, i just picked up a tII, i definately picked up a project. the car doesnt run, its missing a few things like the alternator belt, the battery, the air box, and the problem im lookin at and wondering, there is two plugs on the passenger side that run through the firewall. there is a large round plug and a smaller two prong round plug. i have no idea what those plugs go to, the guy i traded for (traded a s4 na) said the car had been broken into and some electronics stolen (they took the mufflers and spoiler too lol). so my question is what do those plugs go to? i took a pic on my phone, and ill try to have them loaded up this weekend if anyone needs pics. tia for any help.

 

The Factory Service Manuals for all years of RX-7 (and many other rotary cars) can be downloaded for free here: http://foxed.ca/foxed/index.php?page=rx7manual . They contain all common service information information and more, and are an essential tool for any sort of service work that needs to be performed on these cars.

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.

These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download. The Haynes is a good quick reference covering 99% of questions, while the FSMs show complete and detailed procedures.

 

ya take pics and post.The harness that is on that side goes from ECU to engine.
By the way,why would they Break INTO the car to take the mufflers and spoiler???.(.lol!)
