Resolved 1g Mishimoto fan wiring with switch and relay directly to ignition

[JAW91]

Where is the best place to wire the aftermarket Mishimoto fan to the ignitio?. I've searched this before and have come up with no real direct answer or how to on it. Also, I'll clear this up before I get the comments telling me to fix the underlying problem. I soldered the high and low positive and negatives together and made them into two wires (They start as 4 on my car so I made them into 2 and used a new connector) and used a new 2 prong connector on the new wires. My fan didn't work before and its still not working now so I just want to let that stay as it is and wire it directly to the ignition so I don't have to worry about it again.

Oh and this is to a 1991 Talon.

I keep thinking that it should be an easy fix but I can't figure it out for some reason. The relay is brand new and clicks when I flip switch in my car but I'll test the ohms on it tomorrow anyways. The switch positive is wired into my cigarette lighter positive and the switch lights up like it should. I'll test the negatives with my test light tomorrow and see whats up with them (I know the fan ground is good because I put the positive connection on the battery and the fan worked great like it should).

I don't care for those lighted switches, maybe the switch isn't wired up to the right terminals? Two pictures...

Just giving you suggestions, only thing I can think of

I was going to wire in a switch too, until I found out that if you turn the blower on to the first notch, and press the little button with the snowflake on it, both fans come on anyway. There's literally no point in wiring a switch, unless your mixer is stuck on heat or something. -.

That's the Air Conditioner button

Ok, I'm. Not exactly sure what your doing here, but here is an easy solution that I used on my talon. Fused. Power wire from battery to relay. Using 10ga wire. Then from the relay to the fan. Ground the relay. Your switch should be fed from an ign wire. I used the ign wire from my radio as a. Source as my switch is in the cab. Then ign to switch. Input. Ground to ground (I used the radio bracket) and then the output to the relays trigger input. This way you never have to worry about being stupid and leaving your fan running while your out of the car because the ign off means power is off. And the relay is only triggering power. Directly from the battery or disconnecting it. Just make sure your fuse and relay are capable of handling the amperage your fan needs, and also make sure you use the proper. Wiring as well. The feed I suggest 10ga, but the ign trigger can be smaller as it doesn't have much draw to trigger the. Relay.

Those Diagrams are for if you have the stock connectors and fan and I don't have the stock connectors and I have a Mishimoto slimfan. Lol @TurboLaserRS man I have no comment for that xD. I don't have a relay in the spot for my fan because I did not plan on using it anyways. And also, the switch has labels on the side of it telling me whats what so I don't think that's it. I think I have one of the terminal's in the wrong place or something. My problem is that the relay clicks on when I flip the switch but my fan still gets no power.

I'm out of fast fix ideas, you should be able to find the fault with a DVOM though

First take your DVOM and make sure you have +12V at terminal 30. If no voltage on terminal 30, your fuse is blown or the wire before terminal 30 is not connected to +12V.

If good, flip the switch so relay clicks (if it clicks, your relay coil ciruit is correct). Now you will have +12V at terminal 87. If no fan operation, the wire between 87 and fan is open, or the fan ground is open, or fuse just blew

Fixed it, had a broken connector on the fan power wire that I replaced and had the fan power on 87A instead of 87 -_-. Thanks for the help though guys.

Glad you got it figured out

No problem happy to have helped
