I used 1' of wire for each wire, used the same connectors and slipped them on the two prong toggle switch.

You could run the wire from the relay all the way up to the same spot as your other toggle switch, use the gas pedal screw again for the ground as you did for the radiator toggle and have both toggle switches in the same location.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I just did both. I'm hoping to keep my engine temps down on the track. A couple things to make this easier. The relay box is to the right and above the fuse box. It's very hard to read the relay numbers. You want relay number 20 & 22. They are on the bottom row (the row closet to the floor) and last on right (22) and two over (20). If you have fat fingers use a large needlenose to gently pull it out. There are 4 prongs, #85 is the one you use, it's marker on the underside of the relay. Imagine a n,s,e,w when looking at the empty relay socket. # 85 is the e prong. Put some 16/18 wire in the little slit and jam the relay back in, press firmly. Turn your key on and touch the other bare end to some metal, you should hear your fan come on. I routed the wire over some air duct an into the spot for your manuals under your steering wheel. For the ground wire, I unscrewed the screw by the gas pedal, sanded under the head a little to make sure there is bare metal to make a good ground. I stripped the wire 1/2 inch and wound it around the screw and tightened it up. I routed this wire over the air duct also and into the manual spot. I used those little female 1/4" solderless connectors on the wire ends. The single ground wire from the gas pedal slipped onto one of the male ends on the toggle switch. The two wires from the relay box slipped onto the male 2-1 male and this then this slipped onto the other male toggle. I taped the toggle just barely sticking out of the manual holder. Turn your key on, flick the toggle switch and you'll hear both fans turn on. The engine fan is the same but much easier because of the location. The relay box is under the carpet on the drivers side. Put your seatbacks down and pull out the thick foam piece. Unscrew the three nuts pull flip over the silver relay holder. The relay # is 8, it's easy to find since you can read the relay numbers on the relay holder. You use pin # 85 again. Slip the bare wire in and jam the relay back in. I used the front nut where you tighten the relay holder as my grounding location. I used 1' of wire for each wire, used the same connectors and slipped them on the two prong toggle switch. I have my seatbacks down so I have the toggle switch just sitting out of the seam from the thick piece of foam. I left extra wire under the foam for when I need to pull the toggle switch out further. You could run the wire from the relay all the way up to the same spot as your other toggle switch, use the gas pedal screw again for the ground as you did for the radiator toggle and have both toggle switches in the same location. Both mods took about 1.5 hours combined. I bet I could do both in 30 minutes now. I hope I have cooler temps on the track.

Found this thread from a search. Where exactly is the relay carrier #2? I can't seem to find it. I searched behind the rear seats and also on the floor behind the driver side seat. Anybody have a photo? Thx!

POST 3Original post

it is under the carpet behind the rear seat backs.... lift up the carpet, you will see an aluminum cover... it is located under the cover, drivers side.

POST 4 / ORIGINAL POSTEROriginal post

Yep, the relay for the engine compartment mod is behind the rear seats. Pull up the thick carpeting pad, take out a couple screws on the silver piece on the drivers side, flip it over from back to front and you'll see everything. These two mods have lowered my temps on the track.

POST 5Original post

Hey guys, here's a photo of what's behind the rear seats. Still puzzled as to what aluminum cover you're referencing. Aren't the two shown here only for the rollbars? The warning sticker about the rollbars being "spring loaded" has me stopped in my tracks. -- Is the location different in a cabriolet?

POST 6 / ORIGINAL POSTEROriginal post

Your cab is totally different then a coupe. Be real careful with anything to do with the rollbar. I'll look at the picture and see if I recognize anything that looks like a controller.

POST 7Original post

Here's the location in a cabriolet. Photo courtesy of Loren -- renntech.org Important: the relay carrier is located on the engine side, not the back seats side. The convertible top must be raised and stopped about 1/4 of the way (service level) in the air in order to gain access.
