REPAIR OR REPLACEMENT CONTINUED
ECU POWER CABLE CONTINUED
2.
Using electrical tape, attach a length of ibrous twine or 1/4 inch rope approximately 25-30 feet long to end
of ECU power cable (Figure 2, Item 6). This will be the end just removed from circuit breaker box (Figure 2,
Item 2).

Replacing ECU Power Cable.
3.
At electrical connector end of ECU power cable (Figure 3, Item 1), pull ECU power cable (Figure 3, Item
1) through ixed roof beam (Figure 3, Item 2). When ECU power cable (Figure 3, Item 1) has been pulled
completely out of ixed roof beam (Figure 3, Item 2), there should be an adequate amount of twine/rope left
at circuit breaker box (Figure 2, Item 2) end to allow for pulling rope back through with new ECU power cable
(Figure 3, Item 1) attached.
4.
After old ECU power cable (Figure 3, Item 1) has been pulled through, remove twine/rope and attach to new
ECU power cable (Figure 3, Item 1).
5.
At circuit breaker box (Figure 2, Item 2) end, pull twine/rope through ixed roof beam (Figure 3, Item 2) until
correct amount of ECU power cable (Figure 3, Item 1) is extending beyond end of ixed roof beam (Figure 3,
Item 2). A second person at cargo door end guiding and feeding cable (Figure 3, Item 1) into ixed roof beam
(Figure 3, Item 2) will make this procedure easier.
6.
Remove twine/rope.
