like it says, i need a engine wiring diagram. there was a diagram that was plug specific on here a while ago but i cant find it now, i need that one. i need to know were my engine plugs go. so far my temp guage doesn't work and my fuel gauge. any help would be great.

Thank you for your time.

 

Try going to iluvmyRX7.com and downloading the wiring manual from there. The plugs will be listed on each page...

Temp gauge plugs into the block just under and behind the oil filter mount. Look for a small brass plug with a flat electical connector poking out the top (male spade, to be specific).

The temp and fuel gauge share almost NO similar wiring as far as connectors go EXCEPT the ground path for the gauges. Is your oil pressure gauge working at all? How 'bout the tachometer?

 

yeah the oil and the tach work, but the rest doesnt work. even the speedo. i was looking for the color diagram that was on here a few weeks ago. but thank you for your help any thing else would be great.
