wiring question please help

[patsS14]

ok took my car to a shop to get the engine built and my car used to have a big power cord from the battery to the starter. well i get the car back and the power cord is gone and now they got 2 big black/red wires coming out the harness connected to them but i swear before i brought the car those black/red wires were bolted to the frame as grounds??? so are the power wires or groungs??
p.s i traded for this car and they were wired to the frame. so either who ever wired the car first was wrong or the shop i brought it to is

There should be a big power cord to the starter and a little lead. The big lead is battery power and the little terminal lead is crank signal. The starter grounds internally to the block/transmission. The ground line goes from the intake manifold to the chassis ground then to the battery.

Do you have pictures of what they did?

Your post is not descriptive enough, and pictures would help alot. Make it as easy for us to help you.
