My friend and I each recently bought two 2009 Club Car Precedents (IQ) - 6 x 8volt Trojan batteries. Instead of just paying to have someone at a local shop install things like lift kit, tires/wheels, light kit, etc., we decided that we would do some research and do it ourselves. We also thought this would be a good way for us to learn our new carts. So, I bought the MadMax basic light kit and, after a bit of a learning curve, was able to install the basic light kit (dash switch, front bumper/light, and rear lights (w/ bucket harness). Not too bad... except the instructions said there should have been a 'blue wire' at battery #3 to connect the positive end of the battery hook-up (I hooked up the negative black bullet connector of battery hook-up wire to the black bullet connector from behind battery #4 (towards the rear of battery compartment). Getting power was relatively easy .... I just used my voltmeter from the black bullet connector and found out which battery's positive was 16V -- ring connector and I'm good -- all lights work. I realize this will drain these two batteries more than the bank, but I plan on connecting a converter or reducer in a month or so. I still don't know why the MadMax instructions said there would be another 'blue connector' in the battery connector.... the only one i saw was the one off Batt #1 and i know that would give me 48V and that's no good. So, if anybody knows about this mysterious second blue connector, I'd love to know what i'm missing. But, the real question is on my buddy's cart (same as mine). He bought a phantom body kit (he liked the separate headlights instead of the one light bar), but it also came with a premium light kit and harness (bucket harness, taillights, headlights, turn signal, brake light kit, etc.). We hooked everything up and everything worked except the brake lights. We spent hours trying to get the brakes to work. The diagram with the delay and circuit breaker were not great, and when we tested it with a voltmeter, we were getting power (~14V) from the black wire, but nothing from the other two. If anyone has a better picture or instructions on that part (i.e. from the brake switch through the delay and circuit breaker) it would be much appreciated. Finally, he went out to mess with it again today and told me there was a grey bullet connector not plugged into anything on the new light kit harness behind the dash. I told him that on my MadMax Basic Light Kit, it had a grey wire with a red bullet connector that simply connected to the same color on the existing harness. Told him to look for it on the existing harness as it might be hidden with the other wires. Well, apparently he found it and connected it. He didn't think anything of it until he took the cart for a test drive and found that it ran really slow. He got back home and noticed it was in TOW. He switch it to RUN and everything was fine. So, he unplugged that grey bullet and it ran fine in RUN and did NOT run in TOW - back to normal. The only thing we can think of in looking at the Illustrated Parts List ('09-11) is that somehow he linked in/bypassed the TOW switch. Anybody have any idea on this one ? Sorry for the long post.... Just trying to get to know these carts better. Seems like chasing a rabbit down a hole on his brake issue though. I'm going to buy the MadMax Ultimate Upgrade Kit so i get my turn signals, brakes, and horn and see if i have any issues. I think his might be related to the harness and kit that came with the Phantom Kit. Thanks again.
NOTE: I posted this 'fix' long ago. My brake light switch is of a different style, but is also pressure activated. Do the VOM thing on the two leads off the pressure switch to see if it closes/opens under pressure. If it never opens when pressure removed it has failed. If it works normally then the relay has failed....in my opinion. Replacing the relay fixed the problem since my pressure switch was ok. My 09 Precedent electric has this lighting system installed. Headlights, brake lights, horn, tail lights and turn signals. Everything is working OK right now, except the brake lights. The brakes are actuated by a small pressure activated strip switch that has been inserted just behind the rubber brake pedal pad. It's a very small switch. I have checked that out and with foot pressure applied the circuit is completed, and the brake lights should go on. I located the brake relay behind the 'instrument panel'. It is an HDI-048D-A30PMS. It has 4 wires connected. Orange, Blue/White, Green/White, and Black. Two of the terminals are labeled com and NO. I have a Precedent Maintenance and Service manual and the wire color codes match exactly. I also found a nice schematic that shows that the orange and blue/white wires go to the coil and the green/white and blue wires come off the NO contacts. I confirmed with a VOM that the NO contacts are open. I measured the coil resistance and I believe it was/is? in the 2K vicinity. I fiddled with the switch and actually had the brake lights working normally. I put everything back together and the brake lights do not work, again, although everything else still works normally. I shorted out the brake pedal pressure switch and the brake lights still did not work so I do not think that circuit/switch is the problem. So......it certainly appears to me that the brake relay is the culprit.

How To Install Club Car Precedent Brake Light Switch Autozone
The brake light relay mounted under the dash area. If the relay is not present you must install one. Safety First The brake light relay is 48 volt key activated on the coil input. The main contacts are 12 volt positive to the NC (normally closed) contacts on the brake switch. This is where wire colors can vary according to the kit or year of car.
