HEGO ground goes from the ground eyelet tagged with #19 below (orange color wire) to pin 49 at the ECM connector If it's not connected to the back of the LH cylinder head or the intake, it will cause a permanent, and false, lean condition reading in the system.

I'm confused as to what you're asking, then again i've been up for a while...

If you're asking where the loop end goes to (the part that comes out by the intake) It bolts to one of your intake bolts. The other end goes through into the wiring harness on the firewall, into the grommet on the firewall in the passenger side, then down to pin 49 on the computer.

correct me if i'm wrong on that, i'm about 98% sure I got that right. I had to wire a '91 2 weeks ago & I believe either that or an injector went to 49... injector might have been 59... I can double check my manual when I get home & let you know.

Edit: nm, joel beat me to it [&:]
