I just ckd. Auto Zone P/N RB-133 Module = $320.00....P/N 31-396 Dist. = $142.00  Both with Limited Lifetime Warranty is not bad price, but it's best to eliminate everything else First. On the 6 pin connectors to the Module, there should be Voltage or Resistance measurements with key on & off that U should be able to make. U may get them from Dealer or a Good Manual. These are fun cars but I would invest in the necessary Tools & Books to keep it up.   John
