I'm looking in converting my tail light bulbs to LED bulbs. I know that the turn signals would require resistors or a flash relay. I'm on Superbrightleds.com and it gives me the option of either using a electronic flasher or wiring up resistors. My question is where in the car would I plug in this flasher? I'm looking at the CPU but wouldn't this connect into a female plug?
There's an easier solution to the "hyper flash" LED problem that doesn't require the extra resistors or that flasher relay (which BTW is not compatible with our FC's, regardless of what that website said). Basically what you need to do is open up the CPU/flasher unit, and remove the resistor labeled R1 from the circuit - here's a couple of pictures to help locate the R1 resistor, which my pick is pointing to in both pictures. This was for an S5T2's CPU flasher unit, but I think all S5's are the same, and the S4's may be as well. When I did mine, I only de-soldered one of the 2 resistor leads from the board, and put some heat shrink tubing over the resistor & its lead to insulate it and allow for a "reversible" mod. The only function you lose by doing this is if the your LED tail flashers were to fail, the dash indicators won't hyper-flash to let you know. I figure I can live without that, as the LEDs will probably outlast the car.

Thanks I'll give this a shot. I didn't even know about the hyperflash feature. Though I am curious as to how you put heat shrink over the removed/desoldered resistor. You said you only de-soldered one of the 2 resistor leads from the board", are there two R1 Resistors?
Will this affect non-LED bulbs in any way? (The front turn signal won't have LED bulbs)

^There's only one R1 resistor as marked on the board. What I was trying to say is you only need to desolder one of the 2 leads on that R1 resistor from the board. So at that point, you can bend the R1 resistor up from the board a bit, and slip a piece of heat shrink tube over it & its now disconnected lead to insulate it. Make sense?
Not sure how this mod will work if you retain regular turn signal bulbs up front, and only have LEDs in the rear. When I did mine, I did LEDs all around.
Yea, I was going to say just put 1156's in the rear and 1157's in the front as called for but in LED format. Then remove one side of the R1 resistor and cover with heat shrink to prevent contact with nearby components. I'll be doing this soon as I have now done all bulbs in LED except my turn signals.
I just did this to my car today - worked perfectly. This is a super basic level mod. I was originally going to replace with a different resister as per a friend's request and other posts I've seen here, but just breaking the connection logically makes sense, no need to replace it with another resistor. I did a before and after test with removing my front turn signal, I got hyper blinker, then I did the mod and tried again and had normal blinker, beautiful. I'll be removing my rear resistors tomorrow.
Actually, that brings up a thought, are those resistors I still have on the rear blinkers doing any harm now that I did this mod? I mean, I'm going to remove them anyway, but just for my knowledge.

^You can get rid of those added resistors, they are just wasting power & turning it into heat when you use your blinkers now. Which defeats one of the purposes of LED lights - much lower power consumption.
Assuming I replace both front and rear turn signals with LEDs. With this mod would this cause problems to the turn indicators on the cluster which won't be LEDs?

No, the cluster is basically just outputting the results. It won't matter if those are LED or not.

Nope, no problems there. I still have the original bulbs on the dash turn signal indicators; LEDs were swapped into the front & rear external turn signals, brake, parking & side marker lights.
