[09 lex 250]

i am currently using a lrp sxx tc spec with a lrp 7.5 x12 motor i have a yokomo 7.5r zero modifides motor i want to use in the bmax. my question is that will the sensor wire work from the tc spec into the yokomo motor? it fits perfect and all but am very cautious about turning it on!! i really cant afford to buy another speedo right now...any advise would greatly be appreciated

thanks
