i am trying to build my own wiring harness and plan on just using the CKP, MAP, . The CMPis shot and don't plan on using it any ways, purchased TC88 ignition module. don't plan on using bank angle sensor or the TSSM module or even the stock twin cam instrument cluster. have a partial wiring harness, need to know what pins on the cdi or tc88 for the battery voltage + and grounds ,for the crank signal sensor + and - and the three for the map sensor and the stock coil which i have tested which shows spark if i ground the coil, i am not sure if the voltage regulator is working correctly either. with battery at full charge and battery booster connected voltage drops below 12 volts, gonna hook up external computer power supply to cdi by its self to keep voltage at a constant so that the map sensor voltage stays with in the range to correctly work .
