He is a customer of mine and i sent him here. Reposted this here to get more of a response
i have a Heng Long bulldog,(overabarrel) new member, the smoke unit has packed up, can i upgrade and replace unit with a 'proportional' unit?, ive see the propotional unit has 4 extra long wires two green two black, where do they go to??. thanks for your time and response!. 

No idea lol - which is why I didn't answer him. Hopefully someone will see this here and reply

Good luck Overabarrel

it has 2 green 2 black? thats er......weird......

it should just be a connector type that has 1 red and 1 red like the sound

Can you take a pic ofthe proportional unit?

hi the prop smoker has four extra wires two go to each motor , the more speed the more smoke , if it didnt have the extra wires it wouldnt be proportional, lol

the four "extra" wires go directly to the motor feeds Ala propoetional has his puffer given up completly or just leaking a lot as this could be just a leak in the housing and nothing more than a quick repair
