I am putting headers on my friends 95Z, and he got the OVC wire set and the wire looms that bolt to the valve cover bolts, at each bolt there is a bracket with 4,3,or 2 holes for the wires, obviously. I ran the driver side tonight and was pretty much a no brainer. However, on the passenger side, its a PITA. The last time I put OVC wires on I ran the wires behind the power steering pump, under the AC and up to the opti, that might be kind of hard to picture. I tried to put them in the factory location but the taylor wires are to fat and wont stay in, and in fear of a wire meeting the idler pulley I feel I should re route them. So I was wondering what you guys have done. Thanks.

I ran my MSDs on the other side of the PS pump(waterpump side), behind the pulley, then under the alternator. I made sure they were secured with an extra zip tie. I have about 1/4" of clearance between the wires and the PS pump pulley.

 

Mine run above the water pump but below the power steering pump, which might be the way you described. I'm not concerned with them hitting anything as there is really no slack in the wires.
