Hi guys.I have an 86 honda trx125 that i bought from a friend,not a pretty machine but has good compression,etc.I really don't want to invest more money into this beast and am looking just to hot wire key ignition.I have already smashed out old key switch and exposed the green,red,black and blk with white stripe.I have found that with the black and red together i get the nuetral light and headlight to come on when trying to pull start,but no spark to coil.Does one of the remaining 2 wires need to be tied in also?Any help or diagrams would be great,thanks...
