hi im swapping the tail lights in my 99 cobra to the regular red light with a sequentials harness and the relay to to slow them down. what i first did is went and got the female body harness plug at a juckyard that plugs into the harness. so i cut the cobra plug and spliced the wires together matching the colors..so the cobra is a 5 pin plug and the gt or v6 is a 4 pin plug. so on each side i have a dark green wire left. so i cleaned cut it and tape it up. at this time i have turn signals and lights and hazards but no break lights except the 3rd brake light works. so next i went in the kick panel by the hood latch and found the 2 plugs this guy was talking about ran a jumper wire from number 15 to number 12 on the other plug which was both dark green and then my brake lights worked but now the 3rd light wont work.so if you know what i should do to get my 3rd brake light working that would be great... read this on a tread this is what the guy said below
I know that this is a very old post, but I want to add some information to help out anyone that wants to add gt tailights to a cobra harness. Ill make it short, simple and easy.
First off, get a regular gt tailight bulb harnesses and replace your cobra taillight harness with them. Now match up the wires from the gt bulb harness to your existing body harness by either splicing or using a new conector, doesnt matter how you do it just match them up. Light green with orange stipe for the left side and orange with light blue stripe for the right, brown with brown black to black, easy. Now on your body harness you will have a dark green wire left, you will not be using this wire anymore, so tape it off or cut it, it doesnt matter. The leftover dark green wire actually is spliced from the 3rd brake light for use on the cobra only.
At this point your left and right blinkers, hazards, etc. will work with the exception of your brake lights. Now lets get the brake lights working by pulling off the drivers side kick panel. Under the panel you will see 3 plugs just under the hood cable/handle. You will be working on the two square plugs, c331 and c332.
You will not have any brake lights at this time and this is due to the cobra harness using a splice from the 3rd brake light (darkgreen wire) to power them. Youll need to add a jumper from pin number 15 on c331to pin number 12 on c332. Both pin number 15 from c331 and pin number 12 from 332 are dark green, exact same color as the left over wire from your body harness in the trunk (its actually the same wire, it is labled as wire number 569). This jumper will replace the function of the original splice in the trunk from the 3rd brake light that you are no longer using. When your finished your brake lights and blinkers will work as they should.
