ok i have a 92 6 cyl i swapped a carbbed 406 into. and i am having some electrical issues with the dash.... i used the the original 92 headlight harness. but the other part of that harness on the driverside plug is out of my 87 parts car v8 and i have completly gutted the ecm harness out. but my issue is with my dashlights and stuff.. i will put a list of my issues and hopefully yall can give me some pointers. it also has an aftermarket alarm in it but i will be removing that and hopfully that will fix some of my problems thanks

if my headlights are on the securty light on the dash stays on and the car will not start.

my wipers do not work at all

sometime but not all the time. the car will not start. you put the key in turn it the security light will come on along with all the dash and light like normal and when the security light goes off and u tune turn the key to crank it you get nothing... but if i put a jump box or jumper cables on it it will fire up jsut fine.. i thought maybe a bad batter but its not the battery cuz i can turn it off and it will crank right back up like normal... so idk...

may dash light blink when my blinkers do...

the wiring under the dash isnt hacked up so i dont think that is the issue... so if any1 has ne pointers it would be great!
